Answer:
900cm^3
Step-by-step explanation:
1 cm= 10 mm
x=300mm (criss cross)
1cm*300mm/10mm= 10mm*x/10mm
30cm=x
30cm=300mm
1m=100cm
0.2m=x
1m*x/1m=0.2m*100cm/1m
x=0.2*100cm
x=20cm
0.2m=20cm
l=15cm
w=30cm
h=20cm
v=l*w*h
v=15cm*30cm*20cm
v=450cm^2*20cm
v=900cm^3
9000cm^3
Width:300mm=30cm
Height:15cm=15cm
Depth:0.2m=20cm
V=DxWxH
V= 20x30x15
V=9000cm^3
20%
all you do in this is divide the smaller nymber by the bigger number:
600/3000
