a) A side of the solid cube metal =70cm, hence its volume is (70)3 =343,000 cm3
The base of the rectangular solid =6080=4,800cm2
Hence the height of the rectangular solid =
h=71.4583 cm
b) 1m=100cm
Hence 1m3=1,000,000cm3
Therefore the Volume of the rectangular solid =343,000cm3
Converting to m3;
=0.343m3
c) Diagonal of a rectangular solid =
Where Length, l=80cm
Width, w=60cm
Height,h=71.4583cm
Thus the diagonal
=122.90cm
