Question

Length = 12 cm, breadth = 8cm
and Height= 4.5a Find
Volume of
Cuboid, lateral Surface
area and total surface area of cuboid​

Answer 1

Volume of cuboid is 67200 cm³.

Total surface area of cuboid is 19840 cm².

Lateral surface area of cuboid is 18720 cm².

Given :-

Length of cuboid = 70 cm.

Breadth of cuboid = 8 cm.

Height of cuboid =1.2 m = 120 cm.

To find:-

Volume of cuboid.

Total surface area of cuboid.

Lateral surface area of cuboid

Formula Used:-

•Volume of cuboid = Length×Breadth× Height

• Total surface area of cuboid=2(L×B+B×H+L×H)

• Lateral surface area of cuboid=2h(L+B)

Calculations:-

Volume of cuboid= (70×8×120)cm³

= 67200 cm³

Total surface area of cuboid=

2(70×8+8×120+70×120) cm²

=19840 cm²

Lateral surface area of cuboid=2×120(70+8) cm²

=18720 cm²
