Question

Mr. Butterworth baked a chocolate cake in the shape of a square prism. The cake was 12 in. by 12 in. by 5 in. high. He spread chocolate icing on all four sides and the top. How many square inches of icing did he use?

the answer is 486 cm2 but how do I find that answer

To find the total surface area of the square prism cake, you need to find the areas of all six faces and then add them together.

1. The top and bottom faces each have an area of 12 in. × 12 in. = 144 in².
2. The four side faces each have an area of 12 in. × 5 in. = 60 in².
3. The total surface area of the cake is 2(144 in²) + 4(60 in²) = 288 in² + 240 in² = 528 in².

Since Mr. Butterworth spread chocolate icing on all four sides and the top, you need to subtract the area of the bottom face (144 in²) from the total surface area to get the total amount of icing used:

528 in² - 144 in² = 384 in².

Therefore, Mr. Butterworth used 384 square inches of icing on the chocolate cake.

Apologies for the error in my previous response. Let's correct the calculation.

The total surface area of the square prism cake is calculated as follows:

1. The top and bottom faces each have an area of 12 in. × 12 in. = 144 in².
2. The four side faces each have an area of 12 in. × 5 in. = 60 in².
3. The total surface area of the cake is 2(144 in²) + 4(60 in²) = 288 in² + 240 in² = 528 in².

Since Mr. Butterworth spread chocolate icing on all four sides and the top, the total amount of icing used is the same as the total surface area of the cake:

528 in².

Therefore, the correct answer is 528 square inches of icing used on the chocolate cake.

Answer 4

no the answer is 486

Answer 5

Apologies for the confusion. Let's correct the calculation again:

1. The top and bottom faces each have an area of 12 in. × 12 in. = 144 in².
2. The four side faces each have an area of 12 in. × 5 in. = 60 in².

To find the total surface area of the cake:
- Add the areas of all six faces: 2(144 in²) + 4(60 in²) = 288 in² + 240 in² = 528 in².

Since Mr. Butterworth spread chocolate icing on all four sides and the top, you need to subtract the area of the bottom face (144 in²) from the total surface area to get the total amount of icing used:

528 in² - 144 in² = 384 in².

Therefore, the correct amount of icing used on the chocolate cake is 384 square inches. Thank you for pointing out the error.
