Question

How much did hazel spend on the felt

Answer 1

$47.52

Explanation:

First find the area in square inches. - 6*11*8=528

Then multiply the cost per square inch by the area - 528*9=1452

Convert the number into dollars - $14.52

Answer 2

C

Explanation:

Calculate the SA.

`SA = 2(6*11)+2(11*8)+2(6*8) \\ \\ SA=2(66)+2(88)+2(48) \\ \\ SA=132+176+96 \\ \\ SA=404`

Now since we know it costs $0.09 per square inch, we can multiply 0.09 by the SA.

`404*0.09=36.36`

It costs $36.36 in all.
