A cube has a surface area of 96 square inches. What is the volume of the cube
The formula for the surface area of a cube is: SA= 6((length of side)^2).
So if the surface area is 96, first divide by 6. And you get 16. Next you find the square-root of 16 and get 4. So the length of each side is 4 inches.
The formula for volume of a cube is V=(length of side)^3.
So 4 raised to the third power is: 444.
The volume of the cube is 64 inches cubed.
The volume of a cube is 64 cubic inches.
"A cube is a three-dimensional object that has 6 congruent square faces. Dimensions of all the 6 square faces of the cube are the same".
For the given situation,
Surface area of the cube = 96 square inches
Formula for surface area of the cube, A = \(6s^{2}\)
⇒\(6s^{2}=96\)
On dividing by 6 on both sides,
⇒\(s^{2}=16\)
⇒\(s=\sqrt{16}\)
⇒\(s=4\)
The side of the cube = 4 inch
The formula to find the volume of a cube, V = \(s^{3}\)
⇒\(V=4^{3}\)
⇒\(V=64 inch^{3}\)
Hence we can conclude that the volume of a cube is 64 cubic inches.
