Question

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

Answer 1

Answer:

Explanation:

Given :

• Length of a chalk box (l) = 16 cm
• Breadth of a chalk box (b) = 8 cm
• Height of a chalk box (h) = 6 cm

To Find :

• The surface area of a chalk box.

Formula to be used :

• Surface area = 2(lb + bh + lh)

Solution :

★Surface area,

2(lb + bh + lh)

⇒2(16 × 8 + 8 × 6 + 16 × 6)

⇒2(128 + 48 + 96)

⇒2(128+144)

⇒2(272)

⇒ 544 cm^2

Hence, Surface area of a chalk box is 544 cm^2.

Answer 2

$\large\purple{\boxed{\bf{Answer}}}$

Given,

➡ Length of box = 16cm

➡ Breadth of box = 8cm

➡ Height of box = 6cm

To find,

Surface Area of Chalk Box

Solution,

Formula used :-

$\large\pink{\boxed{\sf{Surface Area=2(lb+bh+hl)}}}$

Area = 2[(16×8)+(8×6)+(6×16)]

Area = 2(128+48+96)

Area = 2(272)

$\large\bold\orange{\boxed{\sf{Area=544cm²}}}$

Hope it helps..
