Example Question #1 : How To Find The Volume Of A Figure
What is the volume of a box with a length of 5, a height of 7, and a base of 16?
When searching for the volume of a box we are looking for the amount of the space enclosed by the box. To find this we must know the formula for the volume of a box which is
Using this formula we plug in the numbers for Base, Height, and Length to get
Multiply to arrive at the answer of .
Example Question #54 : Quadrilaterals
The above depicts a rectangular swimming pool for an apartment. The pool is two meters deep everywhere. What is the volume of the pool in cubic meters?
The correct answer is not among the other choices.
The pool can be seen as a rectangular prism with dimensions 24 meters by 15 meters by 2 meters; its volume is the product of these dimensions, or
cubic meters.
Example Question #2 : How To Find The Volume Of A Figure
A cheese seller has a 2 foot x 2 foot x 2 foot block of gouda and she wants to cut it into smaller gouda cubes that are 1.5 inches on a side. How many cubes can she cut?
First we need to determine how many of the small cubes of gouda would fit along one dimension of the large cheese block. One edge of the large block is 24 inches, so 16 smaller cubes would fit along the edge. Now we simply cube this one dimension to see how many cubes fit within the whole cube. .
Example Question #3 : How To Find The Volume Of A Figure
An aquarium is shaped like a perfect cube; the area of each glass face is 1.44 square meters. If it is filled to the recommended 90% capacity, then, to the nearest hundred liters, how much water will it contain?
Note: 1 cubic meter = 1,000 liters.
A perfect cube has square faces; if a face has area 1.44 square meters, then each side of each face measures the square root of this, or 1.2 meters. The volume of the tank is the cube of this, or
cubic meters.
Its capacity in liters is liters.
90% of this is
liters.
This rounds to 1,600 liters, the correct response.
Example Question #1 : How To Find The Volume Of A Cube
Chemicals to clean a swimming pool cost $0.24 per cubic foot of water. If a pool is 6 feet deep, 14 feet long and 8 feet wide, how much does it cost to clean the pool? Round to the nearest dollar.
The volume of the pool can be determined by multiplying the length, width, and height together.
Each cubit foot costs 24 cents, so:
Example Question #11 : How To Find The Volume Of A Cube
The density of gold is and the density of glass is . You have a gold cube that is in length on each side. If you want to make a glass cube that is the same weight as the gold cube, how long must each side of the glass cube be?
Weight = Density * Volume
Volume of Gold Cube = side3= x3
Weight of Gold = 16 g/cm3 * x3
Weight of Glass = 3/cm3 * side3
Set the weight of the gold equal to the weight of the glass and solve for the side length:
16* x3 = 2 * side3
side3 = 16/2* x3 = 8 x3
Take the cube root of both sides:
side = 2x
Example Question #351 : Hspt Mathematics
What is the volume of a cylinder with a diameter of 6, and a height of 5?
Write the formula to find the volume of a cylinder.
The radius is half the diameter, which is 3.
Substitute all the known dimensions into the formula.
Example Question #361 : Problem Solving
Find the volume of the cube if the face of square has a perimeter of .
Find the side length of the square given the square perimeter. The perimeter of a square is:
The side of the cube has a length of one.
Write the formula to find the volume of a cube.
Substitute the side length.
Example Question #2 : How To Find The Volume Of A Figure
One cubic meter is equal to one thousand liters.
The above depicts a rectangular swimming pool for an apartment. The pool is meters deep everywhere. How many liters of water does the pool hold?
The pool can be seen as a rectangular prism with dimensions meters by meters by meters; its volume in cubic meters is the product of these dimensions, which is
cubic meter.
One cubic meter is equal to one thousand liters, so multiply:
liters of water.
Example Question #3 : How To Find The Volume Of A Figure
What is the volume of the rectangular prism below?
The formula for volume of a rectangular prism is
Remember, volume is always labeled as units to the third power.
