Answer:
(A) Small truck
Step-by-step explanation:
The volume of a rectangular prism with length [tex]l[/tex], width [tex]w[/tex], and height [tex]h[/tex] is given by [tex]V=lwh[/tex].
Let's calculate the volumes for each of the trucks:
Small truck: [tex]V=4\cdot 3\cdot 3.5=42\:\mathrm{cm^3}[/tex]
Medium truck: [tex]V=5\cdot 3.\overline{3}\cdot 4=66\frac{2}{3}\:\mathrm{cm^3}[/tex]
Large truck: [tex]V=6.25\cdot 4\cdot 4=100\:\mathrm{cm^3}[/tex]
We're looking for the smallest truck that can hold at least [tex]40\:\mathrm{cm^3}[/tex]. Therefore, our answer is the small truck.
