Question

Fine the total surface area of cuboid whose dimensions are 20cm×25cm×6cm

Answer 1

Answer:

Total Surface Area Of The Cuboid = 1540 cm^2

Step-by-step explanation:

1. Given:

LENGTH = 20 CM

BREADTH = 25 CM

HEIGHT = 6 CM

2. To Find : TSA of a Cuboid

3. Formula

TSA OF CUBOID = 2 (Length x Breadth + breadth x height + Length x height)

4. Substituting all the values known to us in this formula we get:

                            = 2 (25*20 + 25*6 + 20*6)

                            = 2 (500+150+120)

                            = 2 * 770

                            = 1540 CM^2

Therefore, the total surface area of the cuboid is 1540 cm^2.

Answer 2

Given :

Length of cuboid = 20cm

Breadth of cuboid = 25cm

Height of cuboid = 6cm

To find :

Total surface area of cuboid = ?

Solution :

We know that,

TSA of cuboid = 2(lb + bh + lh)

Here,

TSA denotes total surface area of cuboid

• l denotes length of cuboid
• b denotes breadth of cuboid
• h denotes height of cuboid

By substituting all the given values in the formula we get,

→ TSA of cuboid = 2(20 × 25 + 25 × 6 + 20 × 6)

→ TSA of cuboid = 2(500 + 25 × 6 + 20 × 6)

→ TSA of cuboid = 2(500 + 150 + 20 × 6)

→ TSA of cuboid = 2(500 + 150 + 120)

→ TSA of cuboid = 2(650 + 120)

→ TSA of cuboid = 2(770)

→ TSA of cuboid = 1540

Thus, the total surface area of cuboid is 1540cm²$.$
