Answer:
339.12 cubic millimeters
Step-by-step explanation:
The picture of the question in the attached figure
we know that
The volume of the figure is equal to the volume of the two hemispheres (one sphere) plus the volume of the cylinder
so
step 1
Find the volume of the cylinder
The volume is given by

where
B is the area of the base of cylinder
h is the height of cylinder
we have

we have

----> the radius is half the diameter


substitute

step 2
Find the volume of the sphere
The volume is given by

we have
----> the radius is half the diameter
substitute

step 3
Adds the volumes

Volume of the small truck = 554.54 cubic ft
Solution:
Given data:
Length of the small truck =
ft
Width of the small truck =
ft
Height of the small truck =
ft
Volume of the small truck = length × width × height

Let us change the mixed fraction into improper fraction.



= 554. 54 cubic ft
Volume of the small truck = 554.54 cubic ft
