Question

If the sidewall of a cubic structure have length 7m , then find the total surface area.

is this jhit right?​

Answer 1

Surface area of the cube = 294 m²

Explanation:

Sidewall of a cube measures in length = 7 m

Formula for the surface area of a cube = Sum of the areas of all six sides of the cube

= 6 × (Side)²

= 6 × (7)²

= 6 × 49

= 294 m²

Therefore, surface area of the cube is 294 m².
