lume of a prism is given by the following formula
volume = area of cross-section length
example 1
find the volume of each of the shapes shown
area of cross-section
1 x base x height = 5 x 4 * 5 = 10 cm?
5 cm
6 cm
volume = area of canss-section * length = 10 x 6 = 60 cm
4 cm
b)
area of cross-section
ss-section = r2 = 7 * 22 = 41 cm2
or
7 cm
2 cm
volume = area of
c-section length = 41 * 7 = 88.0 cm
