Mathematics

$\boxed{\text{8.7 gal}}$

Step-by-step explanation:

The volume V of a prism is the area of the base b times the height h.

V=bh

Step 1. Calculate the volume of the prism.

Data:

b = 100 in²

h = 20 in

Calculation:

V = 100 in² × 20 in =2000 in³

Step 2. Convert cubic inches to gallons

1 gal = 231 in³

$V = \text{2000 in}^{3} \times \dfrac{\text{1 gal}}{\text{231 in}^{3}}} = \textbf{8.7 gal}\\\\\text{The water jug will hold } \boxed{\textbf{8.7 gal}}$
