Answer 2

Sol: If l, b and h are length, breadth and height of a cuboid, then

• lateral surface area = 2h (l + b)

• total surface area of the cuboid
2(lb + bh + lh)
• volume = lbh If 'a' is the length of the edge of a cube, then

• lateral surface area of the cube = 4a2

• total surface area of the cube = 6a2

• volume = a3

Curved surface area of a cylinder (CSA) = 2πrh.

Total surface area of a cylinder (TSA) = 2πrh + 2πr2 = 2πr(h + r).
Volume of a cylinder (V) = πr2h.

Base area of the cone = πr2

Curved surface area of the cone = πrl

Total surface area of the cone

= πrl + πr2 = πr(l + r)

Volume of the cone = 1 3 πr2h

Surface area of a sphere (A) = 4πr2

Volume of a sphere (V) = 4 3 πr3

Surface area of a hemisphere = 2πr2

Total surface area of a hemisphere = 3πr2

Volume of a hemisphere = 2 3 πr3
