Question

Evaluate the expression 6s2 to find the surface area of a cube with side length s = 3 ft. Question 11 options: A) 54 ft2 B) 36 ft2 C) 324 ft2 D) 3 ft2

Answer 1

54 sq ft

Explanation:

Answer 2

The surface area of cube is 54 sq.ft.

Explanation:

Formula of surface area of cube =
`6s^2`

Length of side cube = s = 3 ft

Substitute the value in the formula:

So, Surface area of cube =
`6s^2=6(3)^2`

Surface area of cube =6(9)

Surface area of cube =
`54 feet^2`

Hence the surface area of cube is 54 sq.ft.
