Question

find the volume of cube whose total surface area is 1350 cm²

Answer 1

as we know that T.S.A of cube= 6a^2
here, 6a^2=1350
a^2=225
a= root225 =15

volume of cube= a^3
here, 15^3 = 3375cm^3......
that's all....,

Answer 2

We know that TSA of a cube = 6a^2

Given TSA of a cube = 1350cm^2.

6a^2 = 1350

a^2 = 225

a = 15.

Length of each edge = 15cm.


Volume of the cube = 15 * 15 * 15

                                  = 3375cm^3.



Hope this helps!
