Question

Find the LSA of cuboid if its length is 8 cm, breadth 6 cm and height 5 cm.​

Answer 1

Answer:

• LSA of cuboid is 140 cm².

Step-by-step explanation:

Given :-

• Length of cuboid is 8 cm.
• Breadth of cuboid is 6 cm.
• Height of cuboid is 5 cm.

To find:-

• LSA or Lateral surface area.

Solution:-

We know,

Lateral surface area of cuboid = 2h(l + b)

• Where, l, b and h are length, breadth and height of cuboid.

Putting the values :

$\longrightarrow$ 2 × 5 × (8 + 6)

$\longrightarrow$ 10 × (8 + 6)

$\longrightarrow$ 80 + 60

$\longrightarrow$ 140

Therefore,

LSA of cuboid is 140 cm².

• Volume of cuboid = lbh

Answer 2

Answer:

$\huge \bf \: Given$

$\sf \: length \: of \: cuboid(l) = 8 \: cm$

$\sf \: breadth \: of \: cuboid \: (b) = 6 \: cm$

$\sf \: height \: of \: cuboid \: (h) = 5 \: cm$

$\huge \bf \: to \: find$

LSA of cuboid

$\huge \bf \: solution$

$\huge \fbox {LSA= 2h(l + b)}$

$\sf \: LSA \: of \: cuboid \: = 2 \times 5(8 + 6)$

$\sf \: LSA \: of \: cuboid \: = 2 \times 5 \times 14$

$\sf \: LSA \: of \: cuboid \: = {140 \: cm}^{3}$
