One piece of leftover plywood is 0.75 inches thick, 3 feet wide, and 7 feet long estimate the approximate surface area of two stacks of 11 pieces of leftover plywood. Round your answer to the nearest hundred

111.6ft^2 for the two stacks

Step-by-step explanation:

0.75inch × 11 = 8.25 inches

8.25 inches = 0.69ft

Here dimensions are 3 ft. Wide, and 7 ft. Long and height of stack = 0.69ft

Surface area of one stack =

2*(LW+WH+LH)

= 2*(7*3 +3*0.69+7*0.69)

= 55.8 ft^2

Multiply by 2 to to get surface area of 2 stacks separately

55.8 × 2 = 111.6ft^2

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
