Question

find the volume of cube whose surface area is 150 m^2

Answer 1

Hey!
Surface area of cube=6a^2
150m^2=6a^2
=)a^2=150/6
=)a^2=25
=)a=5m
so,
volume of cube=a^3
=5^3=125m^3
Hope it helps you

Answer 2

LET a CM BE THE EDGE OF THE CUBE
6A^2=150
A^2 =150/6= a^2 = 25cm=A=5CM
VOLUME OF CUBE =A^3=5^3=125 cm^3
