Quadrilateral 73034

Calculate the volume of the flowerpot in the shape of a quadrilateral prism and how many 20 l packages of soil need to be bought to fill it: dimensions: a = 30cm, height b = 40cm, length c = 120cm.

Correct answer:

V =  144 l
n =  8

Step-by-step explanation:

a=30 cm b=40 cm c=120 cm  V1=a b c=30 40 120=144000 cm3  V=V1 l=V1:1000  l=144000:1000  l=144 l=144 l
V2=20 l  n2=V/V2=144/20=536=751=7.2  n=n2=7.2=8
