0/042>0.036
Step-by-step explanation:
answer: the volume of the composite figure made of two identical pyramids attached at their bases is:
third option 2 [ (1/3)(5)(0.25)(2) ]
solution:
volume of the composite figure: v=?
the composite figure is made of two identical pyramids attached at their bases, then:
v=2 vp
volume of each pyramid: vp
vp=(1/3) ab hp
area of the base of the pyramid: ab
height of the pyramid: hp=2
base of each pyramid is a rectangle with dimensions b=5, h=0.25
ab=bh→ab=(5)(0.25)
replacing in the formula of vp:
vp=(1/3) ab hp
vp=(1/3) (5)(0.25) (2)
replacing in the formula of v:
v=2 vp
v=2 [ (1/3)(5)(0.25)(2) ]
