Answer:
The approximate surface area of two stacks is 111.5 square ft.
Step-by-step explanation:
Given : One piece of leftover plywood is 0.75 in. thick, 3 ft. wide, and 7 ft. long.
To find : Estimate the approximate surface area of two stacks of 11-piece leftover plywood ?
Solution :
The length is 7 ft.
The width is 3 ft.
The height is 0.75 in.
11-piece leftover plywood.
i.e.
Convert inches into ft,
1 inch = ft
8.25 inch = ft
The surface area is
The surface area of two stacks is
Therefore, the approximate surface area of two stacks is 111.5 square ft.

Step-by-step explanation:
Your question isn't complete but let's assume that you want to know the amount of time that she spends working on her homework.
Since we are informed that Ella practices piano for 45 minutes and that she spends m minutes longer working on her homework than she does practicing the piano, the expression to get the number of minutes that she uses on her homework will be:
= 45 + m
For example let's say that she spends 7 minutes more in her homework. Therefore, the total minutes spent on the homework will be:
= 45 + 7
= 52 minutes
