Answer:
400cm²
Step-by-step explanation:
Total surface area of a prism includes the area of the top and bottom triangle sides of the prism, plus the area of all 3 rectangular sides.
Base & Bottom triangle area: 2 x [(8 x 15)/2] = 120cm²
Side triangle area: 17 x 7 + 8 x 7 + 15 x 7 = 280cm²
Total surface area = 280 + 120 = 400cm²
Answer: $210.75
Explanation: You multiply the price of the object by how many they buy.
So for the beams you calculate 3 x 45.25 and get 135.75. For the screws you multiply 6 x 12.50 and that equals 75. Then, for the total price you add the two together, so 135.75 + 75 = 210.75
Another way to do it is (3 x 45.25) + (6 x 12.50) = 210.75
