Answer:
1) a. 72m^3
b. 3.75m^3
c. 91,125 cm^3
d. 1200 m^3
e.1,20,000cm^3
2) a. 6
b. 14.54cm^3
c. 43200cm^3
d. 3m
d. 2dm
Step-by-step explanation:
1) a. volume = l x b x h
=6 x 3 x 4
= 72 m^3
b. volume = l x b x h
= 2.5 x 1.5 x 1
= 3.75m^3
c. volume = l x b x h
= 45 x 45 x 45
= 91,125 cm^3
d. volume = l x b x h
= 30 x 20 x 20
= 1200 m^3
e. volume = l x b x h
= 60 x 50 x 40
= 1,20,000cm^3
2)
a. h= ?
volume = l x b x h
576 = 12 x 8 x h
576 / 96 = h
h = 6 cm
b. l=?
volume = l x b x h
144 = l x 2.2 x 4.5
144 / 9.9 = l
l = 14.54 m
c. volume=?
volume = l x b x h
volume = 120 x 30 x 12
volume = 43200cm^3
d. h=?
volume = l x b x h
168 = 8 x 7 x h
168/56 = h
h = 3m
e. h=? l = 6dm b= 4.5dm
volume = l x b x h
54 = 6 x 4.5 x h
54/27 = h
h = 2dm
