Calculate the surface area of a cube of edge 4 cm. What is the volume?
The volume of a cube can be easily calculated by just using the length of the edge of the cube.
Answer: The surface area of the cube is 96 cm2 and the volume of the cube is 64 cm3.
Let's calculate the surface area of a cube of edge 4 cm and its volume.
Given: Edge of the cube, a = 4 cm
Surface area of the cube = 6a2
= 6 ×(4)2
= 6 × 16
= 96 cm2
Volume of the cube = a3
= 64 cm3
