Question

find the surface and lateral surface area of cuboid whose length, breadth and height are 12cm, 13cm , and 15cm respectively ​

Answer 1

Step-by-step explanation:

Given:-

A cuboid whose length, breadth and height are 12cm, 13cm , and 15cm respectively .

To find:-

find the surface and lateral surface area of the cuboid.

Solution:-

Length of the cuboid(l)=12 cm

Breadth of the cuboid(b)=13 cm

Height of the cuboid(h)=15cm

1)Lateral surface area of the cuboid=2h(l+b) sq.units

=>2×15(12+13)sq.cm

=>30(25)sq.cm

=>750 sq.cm

2)Total surface area of the cuboid=2(lb+bh+hl) sq.units

=>2[(12×13)+(13×15)+(15×12)] sq.cm

=>2(156+195+180) sq.cm

=>2(531) sq.cm

=>1062 sq.cm

Answer:-

1)Lateral surface area=750 sq.cm

2)Total surface area=1062 sq.cm
