Find the surface area of the cube shown below., i don't get this.

37.5

Step-by-step explanation:

As the area of each of the side of the cube are the same we can multiply the area of one side by 6.

The area of one side is

37.5

Step-by-step explanation:

Surface area of a rectangular prism (a cube is a rectangular prism) is 2B + Ph

B is area of the base so do width x length. In cube all side lengths are the same, so do 2.5 x 2.5.

B= 6.25

P is perimeter of base so do 2.5 + 2.5 + 2.5 + 2.5 = 10

P=10

h is the height of the prism, but all sides are the same anyway so it's 2.5

h=2.5

2(6.25) + 10(2.5)

12.5 + 25

37.5
