Answer:
The answer should be 42 ft squared (ft with a small 2 on top/as an exponent.
Explanation:
Using the 2*(W*L+H*L+H*W) formula for rectangular prism surface area, make every variable one of the three numbers, you can choose any numbers for the variables just make sure they are the same number when each variable pops up. For example, make every w as 2, every l as 3, and every h as 3. Remember * is another form of the multiplication symbol. Now we have 2*(2*3+3*3+3*2). Use PEMDAS (Parentheses Exponents Multiply&Divide Add&Subtract) OR BODMAS (Brackets Orders Divide&Multiply Add&Subtract), same things just different terms. First we multiply in the (), 2x3 is 6, 3x3 is 9, 3x2 is 6. Now we have 2*(6+9+6), add in the () and we get 21. All we have is 2*21. Multiply in standard algorithm, an array, grouping, or in repeated addition. You then get 42. Since it’s area you get squared feet. Write this as ft with a small two on the top right/as an exponent number.
