Surface area of a rectangular prism:
L=6cm
W=2cm
H=2cm
SA = 2(H * L) + 2(H * W) + 2(L * W)
= 2(2 * 6) + 2(2 * 2) + 2(6 * 2)
= 2 * 12 + 2 * 4 + 2 * 12
= 24 + 8 + 24
= 56cm²

Volume of a rectangular prism:
L=4cm
W=2cm
H=2cm
V = (L* W) * H
= (4 * 2) * 2
= 8 * 2 = 16cm³
OR
= (area of the base) * H
= 8 * 2
= 16cm³
