Answer 1

hello!

edge=15 cm

TSA of cube=6 a²

=6×15²=1350cm²

hope it helps..♥️

Answer 2

Given:

We have given the edge of a cube is 15cm.

To Find:

The surface area of the cube?

Step-by-step explanation:

We have given the edge of a cube is 15cm.

• For finding the surface area of the cube we must know the formula of the surface area of the cube.
• If a is the side or edge of the cube.
• Then the surface area of a cube is given by the formula $6a^2$.

• Where a is the side of the cube.
• We have side of the cube is 15 which means the value of a is 15cm.
• Thus, the surface area of the cube will be

        $\textrm{surface area}=6(15)^2$

• Now solve the equation written above to get the answer.

       $\textrm{surface area}=6\times15\times15\\\textrm{surface area}=1350cm^2$

Hence, the surface area of the cube is 1350 square centimeters.
