Question

2) The total surface area of a cube is 1350 sq.m. Find its volume​

Answer 1

Answer:

3375 is the volume of cube

Answer 2

We know that Total surface area of the cube is 6a²

A.T.Q.

Total surface area = 1350

or, 6a²=1350

or, a² = 1350/6

or, a² = 225

or, a= √225

or, a= 15

Now we know side of the cube is 15m

Now, volume of cube is a³

Then ,

Volume = (15)³

=15*15*15

=3375

Therefore , the required volume of the cube is 3375 sq.m
