Remember the formula for the volume of a cube.

2764 yd^3

Practice makes perfect

We want to calculate the volume of the cube. Let's see the given measurements of the cube.

The volume of a cube with side length s can be calculated using the following formula. V=s^3 We are given that s= 34. Let's substitute this value into the formula for the volume of a cube!

V=s^3

Substitute

s= 3/4

V=( 3/4)^3

a^3=a* a* a

V=3/4* 3/4 * 3/4

MultFrac

Multiply fractions

V=3* 3 * 3/4* 4 * 4

Multiply

V=27/64

The volume of the cube is 2764 cubic yards.
