Answer 1

Answer:

220 square inches.

Step-by-step explanation:

You have to find the area of each fact on the rectangular prism and add them all up. There are two faces in the prism with each pair of side lengths, like two faces with side lengths of 4x5, two with 5x10, etc.

4x5 = 20 20x2 = 40

4x10 = 40 40x2 = 80

5x10 = 50 50x2 = 100

100 + 80 + 40 = 220 square inches

Answer 2

Answer:

B. 220 in ^2

To find the surface area, we have to find the area of each face and add them all together.

Let's get started.

Face one:

Let's start with the one facing us.

The width is 4

The length is 10

4 x 10 = 40

Since there is an identical face on the opposite side, we need two of those.

40 x 2 = 80

Now let's do the face facing to the right.

The length is 10

The width is 5

5 x 10 = 50

Since there is an identical face on the opposite side, we need two of those.

50 x 2 = 100

Now the one on the top

The length is 5

The width is 4

5 x 4 = 20

Since there is an identical face on the opposite side, we need two of those.

20 x 2 = 40

80 + 100 + 40 = 220
