Answer:
The truck will have to carry the sand on two trip.
Explanation:
Applying,
V = lwh................ Equation 1
Where V = volume of the box truck, l = length of the box truck, h = height of the box truck, w = width of the box truck.
From the question,
Given: l = 1 m, w = 2m, h = 4 m
Substitute into equation 1
V = 1×2×4
v = 8 m³
Since the volume of the box truck is 8 m³, the truck would carry a 9 m³ sand by runing two trip.
First trip: The truck will carry 8 m³ sand
Second trip: The truck will carry the remaining 1 m³ sand
