a)729 mm³, b) 48 km³ and c) 288 m³
1) Let's apply some formulas to get the volume of the following figures:
a) Since all sides are congruent this is a cube. The Volume of a cube is:
V =a³
V = 9³
V =729 mm³
b) In this Rectangular Prism we get the volume by the following formula:
V = a *b* c
V = 3 x 8 x 2
V = 48 km³
c) In this prism, we can find out the Volume by the Base Area (the square of 6 meters) times the height 8 then we can write:
V= Ab * h
V= 6² * 8
V = 36 * 8
V =288 m³
2) Hence, for these first three solids. The Volume is respectively:
729 mm³, 48 km³ and 288 m³
