The formula to finding the Volume of a rectangular prism is
W=width L=length H=height
You have 3 rectangular prisms, you need to find the volume of each one and add them together.
(Going from left to right in rectangular prisms)
(3ft x 2ft x 2.5 ft) + (3ft x 1.75ft x 3ft) + (4ft x 4ft x 2.5ft) = Your answer
I hope this helps :)
(Also, You don't need to use the formula as directly stated, the way I showed for your problem is
![V=(l)(h)(w)](https://tex.z-dn.net/?f=V%3D%28l%29%28h%29%28w%29)
As long as you don't multiply the wrong numbers together{as in mixing up the #s from other rectangular prisms} you should be perfectly fine (: )

Answer:
157,143 mm/s
Step-by-step explanation:
Formula for the volume of a sphere is;
V = 4/3 * pi * r^3
dv/dr = 4 pi r^2
dv/dt = dv/dr * dr/dt
dr/dt = 5 mm/s
dr/dt = 4 * pi * r^2
r = d/2 = 100/2 = 50 mm
dr/dt = 4 * 22/7 * 50^2 = 220,000/7
dv/dr = 220,000/7 * 5 = 157,142.8571428571
Approximately 157,143 mm/s
