Surface Area of a Cuboid

What is the total surface area of a cuboid?

• 2 (l + b)

• 6a²

• 2 (lb + hl)

• 2 (lb + bh + lh)

Find the TSA of a cuboid with dimensions,

l = 5cm, b = 3cm, h = 4cm.

• 54cm²

• 92cm²

• 94cm²

• 62cm²

Find the total surface area of the cuboid.

• 160cm²

• 150cm²

• 148cm²

• 170cm²

Find the LSA of a cuboid of,

length = 80cm

breadth = 40cm

height = 20cm.

• 4800cm²

• 4000cm²

• 3500cm²

• 4200cm²

The LSA of a cuboid is:

• 2h (l x b)

• 2 (l + b)

• 2h ( l + b )

• None of the above

Find the lateral surface area of cube of edge 20cm

• 1600cm³

• 16000cm³

• 800cm³

• 400cm³

Total surface area of a cuboid with length = 60 cm, breadth = 30 cm and height = 40 cm is equal to _________.

• 10800 cm²

• 10860 cm²

• 10820 cm²

• 10080 cm²

Answer explanation

Total surface area of cuboid = 2(lb + bh+ lh) = 2(60 × 30 + 30 × 40 + 60 × 40) = 2 (5400) = 10800 cm² So, Option 1 is correct.

Lateral surface area of a cuboid with length = 90 cm, breadth = 40 cm and height = 60 cm is equal to ________.

• 15650 cm²

• 15620 cm²

• 15635 cm²

• 15600 cm²

Answer explanation

Lateral surface area of cuboid = 2h (l + b) = 2 × 60 (90 + 40) = 2 × 60 × 130 = 15600 cm² So, Option 4 is correct.
