Question

Find the surface area of a chalk box whose length, breadth and height are 16 cm, 8 cm and 6 cm, respectively​

Answer 1

Step-by-step explanation:

L is 16 cm. B is 8 cm. 6 cm is H

Answer 2

Given :-

• Length = 16
• Breadth = 8 cm
• Height = 6 m

To Find :-

• Surface area of chalk box = ?

Solution :-

• It is given that chalk box whose length, breadth and height are 16 cm, 8 cm and 6 cm, respectively. chalk box is in the cuboidal shape. So, here we will use the formula of surface area of cuboid :]

Let Length be 'l' , Breadth be 'b' and height be 'h' .

→ Surface Area of cuboid = 2(lb + bh + hl)

→ Surface Area of cuboid = 2(16 × 8 + 8 × 6 + 6 × 16)

→ Surface Area of cuboid = 2(128 + 48 + 96)

→ Surface Area of cuboid = 2(272)

→ Surface Area of cuboid = 544 cm²

Therefore,the surface area of a chalk box is 544 cm².
