Answer:
234 lb
Step-by-step explanation:
Data:
D = 62.4 lb/ft³
l = 2.5 ft
w = 1 ft
h = 1.5 ft
Calculations:
Step 1. Find the volume of the fish tank
The formula for the volume V of a rectangular solid is
V = lwh
= 2.5 ft × 1 ft × 1.5 ft
= 3.75 ft³
Step 2. Calculate the mass of the water
Density = mass/volume
D = m/V Multiply each side by V
m = V×D
= 3.75 ft³ × (62.4 lb/1 ft³)
= 234 lb
