Question

find the Total surface area and Lateral surface area of a cuboid with length = 3.5cm breadth = 32dm and height = 260cm.

Answer 1

TSA is 18684cm square and lateral surface is 18460cm square

Answer 2

Solution :-

Length = 3.5 cm

Breadth = 32 dm
= 32*10 cm
= 320 cm (1 dm = 10 cm)

Height = 260 cm

Total surface area of cuboid = 2(L*B + B*H + H*L)

⇒ 2(3.5*320 + 320*260 + 260*3.5)

⇒ 2(1120 + 83200 + 910)

⇒ 2*85230

Total surface area = 170460 sq cm


Curved surface area of cuboid = 2H(L + B)

⇒ 2*260(3.5 + 320)

⇒ 520*323.5

⇒ 168220 sq cm
