A lateral surface area of cube is 256m2. Find its volume?
Answers
Given
The lateral surface area of cube = 256m2
Let us consider
a = Side of the cube
The total surface area of a cube = 6 × (side)2
The lateral surface area of a cube of the side a = 4 × (side)2
The lateral surface area of a cube = 4 × (a)2
256 = 4a2
a2 = 256/4
a2 = 64
a = 8m
Side of the cube is 8m.
The volume of the cube = a3
The volume of the cube = 83
The volume of the cube = 512m3
The volume of the cube is 512m3.
