Question

Find the total surface area of a cuboid of length 2 cm, breadth 10 cm, and height 5 c​

Answer 1

   TSA = 2 (lw + wh + hl)

∴  TSA = 2 [(2x10) + (10x5) + (5x2)]

∴   TSA = 2 x 20 x 50 x 10

∴   TSA = 20000 cm³

Answer 2

★ Given :

• Length = 2cm

• Breadth = 10cm

• Height = 5cm

★ To find :

• Total surface Area

★ Solution :

Total surface Area = 2 (lb + bh + hl)

↦ 2 (2 × 10) + (10 × 5) + (5 × 2)

↦ 2 (20 + 50 + 10)

↦ 2 × 80

↦ 160 cm²

More To Know....!

Surface Area of Cube = 6a²

Surface Area of Cone = πr(L + R)

Surface Area of Cylinder = 2πr(H + R)

Surface area of Sphere = 4πr²

Surface area of Hemisphere = 3πr²
