5m
Hver side/lengde er 5m
O= 5*8= 40 m^2
V= pi*r^2*h
V= 3,14 * 20 * 20 *40 =
50 240 cm^3 * 0,001 = 50,24
4*pi*r^2=4*3,14*50cm*50cm=31400cm^2:2
=15700cm^2

V = 40 cm * 40 cm * 40 cm = 64 000 cm^3
64 000 cm^3 * 0,001 = 64 l
Konlusjon: blomsterpotta formet som en kube trenger mest jord
Areal av sirkel * 2 * arealet av rektangelet
3,14 * 2m * 2m = 12,56m^2
12,56m * 2 = 25,12m^2
25,12m * 2m = 62,8m^2
