Answer:
The mass of the apples in the box are 1145.95 lb.
Step-by-step explanation:
Given that,
Width = 3.5 ft
length = 3.5 ft
Depth = 2.75 feet
Density = 49.3 lb/ft³
We need to calculate the volume
Using formula of volume

Put the value


We need to calculate the mass
Using formula of density


Put the value into the formula


But porosity is 31 % so apples is 69% mass of total container.
So, Total mass in pounds is


Hence, The mass of the apples in the box are 1145.95 lb.
