Answer:

The height of the trough is about 1.5 ft

Step-by-step explanation:

If each cubic foot of water contains about 7.5 gallons.

Then; 315 gallons is about $\frac{315}{7.5}=42ft^3$

Let h be the height of the trough, then

$7\times 4\times h=42$

This implies that;

$28h=42$

Divide both sides by 28 to get:

$h=\frac{42}{28}$

$\therefore h=1.5$

The height of the trough is about 1.5 ft
