Question

1. the bakery makes square 2-layer cakes for $45. each layer measures 12 inches long by 12 inches wide. they are 1.5 inches thick. if the bakery puts icing between the two layers, how much icing will the bakery use on each cake?

Explanation:

Step1: Identify icing's shape dimensions

The icing between the two square layers forms a rectangular prism with length $l=12$ inches, width $w=12$ inches, and thickness (height) $h=1.5$ inches.

Step2: Calculate volume of icing

Use the rectangular prism volume formula $V = l \times w \times h$.
$V = 12 \times 12 \times 1.5$
$V = 144 \times 1.5$
$V = 216$

Answer:

216 cubic inches
