Question

Find the length of a wooden plank of 0.25 m of width 2.5 m thikness 0.025 m and volume 0.25 m cube.

Answer 1

Answer:

length = 0.4 m

Step-by-step explanation:

volume= length x width x height

let y = length

0.25= y x 0.25 x 2.5

0.25 = 0.625y

0.25/0.625 = y

0.4 = y

Therefore, the length of the wooden plank is 0.4 m

Answer 2

Answer:

Step-by-step explanation:

Here,

↪V is the volume,

↪L is the length and,

↪H is the height.

Put their values and find the length of the given rectangle.

➡$\sf{}:\implies 0.25=L\times 0.025\times 2.5:$

➡$\sf{}:\implies 0.25=L\times 0.0625$

➡$\sf{}:\implies \dfrac{0.25}{0.0625}$

➡$\sf{}:\implies L=0.25\div 0.0625:$

➡$\sf{}:\implies L=\dfrac{25}{100}\div \dfrac{635}{1000}:$

➡$\sf{}:\implies L=\dfrac{25}{100}\times \dfrac{10000}{625}:$

➡L=4m

✡extra information✡

area of a rectangle= length×breadth

1 cm = 10 mm

1 m = 100 cm

1 m = 10 dm

✡what is area?✡

The measure of the surface and closed by a plane figure is called its area.

Area of rectangle = L × B

here,

L = Length

B = Breadth
