Answer:

Explanation:

To find the surface area of the prism we need to add up the areas of each side.

-To find the area of the two congruent, smaller sides, we will use the equation A = base × height.

i. 3 ft × 2 ft = 6ft² (remember to multiply the units too!)

ii. Since there are two of these sides, we will multiply the area by 2.

iii. 6ft² x 2 = 12 ft²

-To find the area of the two congruent, medium sides, we will use the equation A = base x height as well.

i. 8 ft x 2 ft = 16 ft²

ii. Since there are two of these sides, we will multiply the area by 2.

iii. 16ft² x 2 = 32 ft²

-To find the area of the two congruent, larger sides, we will use the equation A = base x height one last time.

i. 8 ft x 3 ft = 24 ft²

ii. Since there are two of these sides, we will multiply the area by 2.

iii. 24ft² x 2 = 48 ft²

-Now to find the TOTAL surface area of the prism, we will add the areas that we found.

i. 12ft²+32ft²+48ft² = 92ft²
