2 in.
8 in.
4 in.
9 in.
3 in.

Explanation:

Step1: Calculate top prism volume

$V_1 = 15 \times 8 \times 2 = 240$

Step2: Calculate middle prism volume

$V_2 = 9 \times 3 \times 4 = 108$

Step3: Calculate bottom prism volume

$V_3 = 6 \times 1 \times 2 = 12$

Step4: Sum all volumes

$V = V_1 + V_2 + V_3$
$V = 240 + 108 + 12$

Answer:

360 cubic inches
