Answer:
500 sq in. & 9478.85 sq. cm
Step-by-step explanation:
Given:
Cuboid,
l = 15 in.
b = 10 in.
h = 4 in.
Cylinder,
r = 26 cm
h = 32 cm
To Find:
Surface Area = ?
Solution:
Surface area of cuboid = 2(lb + bh + lh)
Surface area of cuboid = 2{15(10) + 10(4) + 15(4)}
Surface area of cuboid = 2(150 + 40 + 60)
Surface area of cuboid = 2(250)
Surface area of cuboid = 500 sq in.
Surface area of cylinder = 2x pi x r( r + h)
Surface area of cylinder = 2 x 22 x 26(26 + 32) / 7
Surface area of cylinder = 2 x 22 x 26 x 58 / 7
Surface area of cylinder = 9478.85 sq. cm
