2 thoughts on “find the total surface area and lateral surface area of cuboid whose length breadth and hight is 20cm 15cm and 18cm. ”
Answer:
The surface area of a cuboid can be mathematically represented by the equation: 2lw+2wh+2hl, where l = length, w = width (or breadth), and h = height. Since we are given all of these values, all we need to do is plug it into the equation. Doing so would result in an answer of 1300 cm2.

Given-
Lenght=20cm.
breadth =15cm.
height =18cm.
To find:
Total surface area and lateral surface area of cuboid.
Solution:
Lateral surface area :
= 2h (l + b)=2h(l+b)
=2× 18( 20+15)
= 35× 71
= 2485cm²
Total surface area
= 2(lb + bh + hl)=2(lb+bh+hl)
= 2(20×15+15×18+18×20)
= 2( 300+270+360)
= 2(930)
= 1860cm²
Hence, Lateral surface area of cuboid is 2485cm²and Total surface area is 1860cm².
