Question

Find the total surface of a cuboid of
dimensions 2m X 1.5m x 75 cm?​

Answer 1

• Given

Dimensions of a cuboid -

• Length of a cuboid = 2 m
• Breadth of a cuboid = 1.5 m
• Height of a cuboid = 75 cm

• To find

• Total surface area of cuboid

• Solution

As we know,

• 1 cm = 0.01 m

Height of cuboid = 75 cm = 0.75 m

Total surface area of cuboid = 2(lb + bh + hl)

Substitute the given values,

⇒ 2(2 × 1.5 + 1.5 × 7.5 + 7.5 × 2)

⇒ 2(3 + 11.25 + 15)

⇒ 2(29.25)

⇒ 58.5 m²

• Total surface area of cuboid = 58.5 m²

Know More -

Cuboid -

• Total surface Area = 2 (Length × Breadth + breadth × height + Length × height)
• Volume =  (length × breadth × height)
• Perimeter = 4 (length + breadth + height)

Cube -

• Total surface area = 6 × $\sf{(side)^2}$
• Volume = $\sf{(side)^3}$
• Perimeter = 12 × side
