Question

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

Answer 1

Given: The dimensions of box 16cm , 8cm and 6cm

To find:  the surface area of a chalk box.

Solution:

• Now we have given:

                 length = 16 cm

                 breadth = 8 cm

                 height = 6 cm

• The total surface area of the box is:

                 2(lb + bh + hl)

                 2 ((16x8) + (8x6) + (16x6))

                 2 (128 + 48 + 96)

                 2 (272)

                 544 cm^2

Answer:

             So the total surface area is 544 cm^2

Answer 2

Step-by-step explanation:

Solution :- Given that ,

length =16cm ,

breadth =8cm,

heigh =6cm

Now ,

The surface area of the chalk box is

$2(lb + bh + hl)$

$2(16 \times 8 + 8 \times 6 + 6 + 16)$

$2(128 + 48 + 96)$

$2 \times 272$

$544 \: {cm}^{2}$

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