a.
cylinder: V=+b+h+=+pi%2A+r%5E2+%2Ah+
if r=10mm, h=25mm, then

V=pi%2A+%2810mm%29%5E2+%2A25mm+
V=pi%2A100mm%5E2+%2A25mm+
V=2500%2Api%2Amm%5E3+
V=2500%2A3.14%2Amm%5E3+
V=7850mm%5E3+


b. rectangular prism V=+a+b+h
if a=20mm, b=8mm, h=6mm, then
V=20mm%2A+8mm%2A+6mm
V=960mm%5E3

c. equilateral triangle
V=%281%2F2%29%2Alength%2Awidth%2Aheight
length=4in, width=5in, height=7in
V=%281%2F2%29%2A4in%2A5in%2A7in
V=%281%2F2%29%2A140in%5E3
V=70in%5E3
