Question

Surface area is determined by the following formula: where s represents the side length.

The figure below is a cube with side length 5 cm.




Which numerical expression represents the surface area of the cube? What is the surface area of the cube?

A.
The numerical expression is 6(5)2
The surface area is 150 cm2


B.
The numerical expression is 652
The surface area is 4,225 cm2


C.
The numerical expression is 6(5)2
The surface area is 900 cm2


D.
The numerical expression is 6 • 52
The surface area is 60 cm2

Answer 1

A choose AAAAAAA!!

trust me you have to choose A i just got it right

Answer 2

Option A

The numerical expression is 6 (5)²

The surface area is 150 cm²

Explanation:

Surface Area of a cube = 6 x length²

therefore the numerical expression is 6 (5)²

and the Surface area = 6 x (5)²

= 6 x 25

= 150 cm²
