Answer:
6 horsepower pump is needed.
Step-by-step explanation:
length of the base =64cm
height of the pyramid =12cm
volume of squar based pyramid= V= a^2 h/3
=64^2 × 12/3 =16384 cm^3
we have 6 hp pump to humidify 25000 cm^3 and 10 hp pump to humidify 50000 cm^3 .
as the volume is 16384 cm^3 we need 6 hp pump.
