Question
Find the side of a cube whose surface area is 600 cm2.
Solution
Given that, surface area of cube = 600 cm2
Let the length of each side of the cube be l
Surface area of cube = 6 (Side)2
600 cm2 = 6l2
`l^2 = 600/6`
l2= 100 cm2
taking square root
l = 10 cm
Thus, the side of the cube is 10 cm.
