Question

Consider the net of a rectangular box where each unit on the coordinate plane represents four feet. If a sheet of plywood measures 4 ft x 8 ft, how many sheets of plywood will a carpenter need to build the box?

A) 3
B) 4
C) 5
D) 6

Answer 1

C

Explanation:

Answer 2

The area of a sheet of plywood is:
A1 = (4) * (8)
A1 = 32 feet ^ 2
The area of the box is given by:
A2 = (16) * (8) + (2) * (16)
A2 = 160 feet ^ 2
The number of sheets of plywood is:
N = A2 / A1
N = 160/32
N = 5
Answer:
a carpenter will need 5 sheets of plywood to build the box.
C) 5
