Question

Find the volume of the cube whose surface area is 2400metre square

Answer 1

S.A = 2400 m²
S.A = 6a²
2400 = 6 * a²
400 = a²
a = 20 m
now,
volume = a³
= 20³
= 20*20*20
= 8000 cm³ 
 
i hope it helps..............

Answer 2

Surface of cube = 2400 m²
6 a² = 2400
a² = 400
a = 20

So,

Volume of cube = a³
Volume of cube = 20³
Volume of cube = 8000 m³
