I have got this answered this but instructor give me comments of wrong answers

Sergio039 [100]

Answer:

2 cubic feet

Step-by-step explanation:

Convert all the lengths to feet round them to tenths then multiply them.

The answer you have got should be also correct as you have multiplied all the lengths then converted to cubic feet. Since your instructor has said that this is wrong this seems to be the only option remaining.

1 feet = 12 inches

$12"=\frac{12}{12}=1'$

$14"=\frac{14}{12}=1.16=1.2'$

$20"=\frac{20}{12}=1.66=1.7'$

$1\times 1.2\times 1.7=2.04=2.0\ ft^3$

A stack of 6 gift boxes is 12.36 inches high. What is<br> the height of 32 gift boxes?

Rom4ik [11]

Answer:

Step-by-step explanation:

Discussion

6 gift boxes are 12.36 inches high

32 gift box are x inches high

This is a proportion question. A proportion is made of 2 equal ratios. If you know 3 parts of the proportion, you can solve for the 4th,

6/32 = 12.36/x Cross multiply

6x = 12.36 * 32 Combine the right.

6x = 395.52 Divide by 6

6x/6 = 395.52/6

x = 65.92

Answer: 65.92

Note

Using a proportion saves you the trouble of finding 1 box and multiplying whatever number you get by 32
