Question

the total surface area of a wooden cube is 21600 cm square find the length of its side​

Answer 1

Answer:

they gave total surface area of cube =21600cm²

TSA =6a²

=6(a) ²=21600

a²=21600/6

a²=3600

a=√3600

a=60

hence the the side is 60

Answer 2

Given,

• The total surface area of a wooden cube is 21600 cm².

To find,

• We have to find the length of its side​.

Solution,

We can simply find the length of the side of the wooden cube by using the following formula:

              The total surface area of the wooden cube = 6 * (side)²  (*)

The total surface area of a wooden cube is 21600 cm²

Using (*), we get

          6 * (side)² = 21600

                 (side)² = 21600/6

                 (side)² = 3600

                  side  = $\sqrt{3600}$

                  side  = 60 cm

Hence, the total surface area of a wooden cube is 21600 cm square then the length of its side is 60 cm.
