Question

Lateral surface area of cube is 900 cm2 find its volume

Answer 1

surface area of cube is = 6*a*a =900 
hence a*a = 900/6 = 150 
hence a = square root of 150 = 12.25 
now volume of cube is = a*a*a 
hence volume will be = 12.25*12.25*12.25 = 1838.27cm3

Hope it helps..If any doubt is there then comment

Answer 2

Lateral Surface Area of Cube = 4a^2
so,
4a^2=900
a=15
Now volume is 15^3=225
