Kaylee found the surface area, in square inches of a rectangular prism by using this formula.

2 (5 * 3) + 2 (5 * 8) + 2 (3 * 8)

What is the surface area of the prism, in square inches?

158

238

40

85

The surface area is 158 sqr inches

Step-by-step explanation:

As Kaylee has already written the formula so we just solve it

= 2 (5 * 3) + 2 (5 * 8) + 2 (3 * 8)

= 2 (15) + 2 (40) + 2 (24)

= 30 + 80 + 48

= 158

158 in^2

Step-by-step explanation:

To determine the surface area of a rectangular prism, the Equation is:

Surface Area = (length x width + width x height + length height) x 2

The surface area with:

length of 2 (5 x 3), a width of 2 (5 x 8), a height of 2 (3 x 8)

SA = 2 (15) = 30, SA = 2 (40) = 80, SA = 2 (24) = 48,

SA = 30 + 80 + 48

SA = 158 square units.

SA = 2LW + 2LH + 2HW

SA = 2 (5 x 3) + 2 (5 x 8) + 2 (3 x 8)

SA = 2 (15) + 2 (40) + 2 (24)

SA = 30 + 80 + 48

SA = 158 in^2

So, your answer is: 158 in^2
