Question

the length,the breadth and the thickness of a rectangular box are 4.234 m,1.005 m and 2.01 cm respectively.Find the area and volume of the box to correct significant figures.​

Answer 1

Answer:

Area = 8.721m²

volume =0.0855m²

Answer 2

Answer:

• area = 4.255 m^2
• volume = 0.0855 m^3

Step-by-step explanation:

Question :-

the length,the breadth and the thickness of a rectangular box are 4.234 m, 1.005 m and 2.01 cm respectively.

Find the area and volume of the box to correct significant figures.

Given :-

• length of a rectangular box = 4.234 m
• breadth of rectangular box = 1.005 m
• thickness of box = 2.01 cm = 0.0201 m

Solution :-

$Area = length \times breadth$

$Area = 4.234 \: m \times 1.005 \: m$

$Area = 4.25517 \: \: {m}^{2}$

$Area = 4.255 \: \: {m}^{2}$

and

$Volume = length \times breadth \times thickness(in \: m)$

$= 4.234 \: m\times 1.005 \: m \times 0.0201 \: m$

$= 0.0855... \: {m}^{3} \: (approx)$
