i have a fish tank size of 2.75feet length,1.5feet breadth, 2.5feet height.How many litres it ll require?

Question

how to calculate ??.What will be formula??? any one plz help me.........

Answer 1

Vol. of tank = L*B*H
Vol. of tank = (2∙75)*(1∙5)*(2∙5)
Vol. of tank = 10∙3125 ft.^3.

Convert to inches cubed:
1 ft^3 = 12^3 in^3
10∙3125 * 12^3 =
10∙3125 * 1728 = 17,820 in^3.

1 in = 2∙54 cm.
1 in^3 = 2∙54*2∙54*2∙54 cm^3.
1 in^3 = 16∙387 064 cm^3.

But 1 Litre = 1000cm^3.
1 Litre = 1000/ 16∙387 064 = 61∙023 744 09 in^3

Vol. of tank / Vol. of litre = 17820 / 61∙023 744 09
Vol. of tank / Vol. of litre = 292∙017 4805 Litres
Vol. of tank / Vol. of litre ≈ 292 Litres.

So let's consider a formula now !

1ft^3 = 1728cm^3
1 in^3 = 16∙387 064 cm^3
1 L = 61∙023 744 09 in^3
1 L = 1000 cm^3.

(Vol. ft^3) * 1728/1 * 16∙387064/1 * 1 L/ 1000 cm^3 =
(Vol. ft^3) * 28∙316 4659 = (Answer) Litres.

Let's check with the about calculation.
(Vol. ft^3) * 28∙316 4659 = (Answer) Litres.
(10∙3125 ft^3) * 28∙316 4659 = 292∙017 4805 Litres.
Answer confirmed.

Answer 2

dont worry, about the water.........
u dont need to calculate also...........
u dont just fill it till the brim(top)...........thats it........
there should be some space above the water...
its ure wish.........

well if u want mathematic....then

Vol. of tank = L*B*H
Vol. of tank = (2∙75)*(1∙5)*(2∙5)
Vol. of tank = 10∙3125 ft.^3.

Convert to inches cubed:
1 ft^3 = 12^3 in^3
10∙3125 * 12^3 =
10∙3125 * 1728 = 17,820 in^3.

1 in = 2∙54 cm.
1 in^3 = 2∙54*2∙54*2∙54 cm^3.
1 in^3 = 16∙387 064 cm^3.

But 1 Litre = 1000cm^3.
1 Litre = 1000/ 16∙387 064 = 61∙023 744 09 in^3

Vol. of tank / Vol. of litre = 17820 / 61∙023 744 09
Vol. of tank / Vol. of litre = 292∙017 4805 Litres
Vol. of tank / Vol. of litre ≈ 292 Litres.

So let's consider a formula now !

1ft^3 = 1728cm^3
1 in^3 = 16∙387 064 cm^3
1 L = 61∙023 744 09 in^3
1 L = 1000 cm^3.

(Vol. ft^3) * 1728/1 * 16∙387064/1 * 1 L/ 1000 cm^3 =
(Vol. ft^3) * 28∙316 4659 = (Answer) Litres.

Let's check with the about calculation.
(Vol. ft^3) * 28∙316 4659 = (Answer) Litres.
(10∙3125 ft^3) * 28∙316 4659 = 292∙017 4805 Litres.


all the best...keep good fish

Answer 3

V = 2.75 x 1.5 x 2.5 ft³
V = 10.3 ft³
V = 291.7 litres
