Question

Find the total surface area and lateral surface area of cuboid whose dimensions are-: length=5dm breath=45dm height=3dm​

Answer 1

Answer: The lateral surface area of a cuboid is 300cm ^2

Total surface area of cuboid is 750sq.cm

Step-by-step explanation:

Given.

Length=5 cm

breadth=45 cm

height=3 cm​

We have to find the lateral surface area of a cuboid using the formula,

Lateral Surface Area of cuboid=2(l+b)h

=2(5+45)3

=2x50x3

=300cm ^2

The lateral surface area of a cuboid is 300cm ^2

Total surface area of cuboid=2(lb+bh+lh)=2(5×45+45×3+5×3)

=2(225+135+15)

=2x375

=750sq.cm

Total surface area of cuboid is 750sq.cm
