Question

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

Answer 1

Answer:

3, 375 cubicmeters

Step-by-step explanation:

Let the length of the edge or side of a cube be = a meters

surface area of one face of a cube = a²

There are 6 equal faces on a cube.

Total surface area of a cube = 6 a² = 1, 350 square meters.

            a² = 1, 350 / 6 = 225  

              a = 15 meters

   Volume is equal to a³ = 15 * 15 * 15 cubic meters = 3, 375 cubicmeters

Answer 2

TSA OF CUBE =1350 sq.m

6l*2 = 1350


l*2 = 1350/6



l*2 = 225


l=15 m

volume of cube =l*3

= 15*3

= 3375 m*3
