Question

Find the total surface area of a cuboid of length,breadth and height as given below 6cm,5cm,4cm​

Answer 1

Answer:

the answer of this question is

total surface area =2(lb+bh+hl)

length =6

breadth=5

height =4

=2(6×5+5×4+4×6)

=2× 74

=148

hope it will help you

Answer 2

Given:

A cubiod with

• Length = 6 cm
• Breadth = 5 cm
• Height = 4 cm

What To Do:

We have to find the total surface area of the cubiod.

How To Find:

To find the total surface area of the cubiod we will use the formula,

• TSA of cubiod = 2(lb + bh + hl)

Solution:

Using the formula,

⇒ TSA = 2(lb + bh + hl)

Substitute the values,

⇒ TSA = 2(6 × 5 + 5 × 4 + 4 × 6)

Multiply the numbers,

⇒ TSA = 2(30 + 20 + 24)

Solve the brackets,

⇒ TSA = 2 × 74

Multiply the numbers,

⇒ TSA = 148 cm²

∴ Hence, the total surface area of cuboid is 148 cm².

Formula Used:

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

Where,

• L = Length
• B = Breadth
• H = Height
