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
