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
(to 1 d. p.)

what’s the answer

According to a study conducted in 2015, 18% of shoppers said that they prefer to buy generic instead of name-brand products. suppose that in a recent sample of 1500 shoppers, 315 stated that they prefer to buy generic instead of name-brand products. at a 5% significance level, can you conclude that the proportion of all shoppers who currently prefer to buy generic instead of name-brand products is higher than .18? use both the p-value and the critical-value approaches.
