Question

the total surface area of a cube is 1350 square metres find its volume

Answer 1

let the side of cube be a.
T.S.A of cube =1350m²

A.T.Q.
6a²=1350
a²= 1350/6
a²=225
then, a =15

now, volume of cube=a³
therefore,
v= (15)³
v = 3375m³

here is ur answer

Answer 2

Hi.

Good question...Keep progressing...

Here is your answer---

Given---

Total surface area of the cube = 1350 m^2

Let the side of the cube be a m.

We know, T.S.A of the cube = 6 x a^2
                                      1350 =  6 x a^2
                                           a^2 =  225
                                               a = √225
                                                a = 15 m
Using the formula,
           Volume of the Cube = a^3
              Volume of the cube = 15^3
                Volume of the cube = 3375 m^3
 -----------------------------------------------------------------------
                                             

Thus, the volume of the cube is 3375 m^3.
