How can I work out how many litres my suitcase is? It's measurements are 50 cm tall,37 cm wide and 20 cm depth.i can't rememeb math class?

1 liter = 1000 cm^3.
The volume of your suitcase is
50 cm x 37 cm x 20 cm
= (1000 cm^2) x (37 cm) = 37 liters.

Volume
= (50 cm) × (37 cm) × (20 cm)
= 37000 cm³
= (37000 cm³) × (1 L / 1000 cm³)
= 37 L

Your suitcase is shaped like a rectangular solid. To determine its volume, multiply length by width by depth. The unit of the answer is cubic centimeters. One liter is 1000 cubic centimeters.

V = 50 * 37 * 20 = 37,000 cm^3
This is exactly 37 liters.

1 liter = 1000 cm³ = 1000 ml

Start with that.

50 x 37 x 20 = 37000 cm³

37000 cm³ / 1000 = 37 liters

Ans. 50*37*20/1000=37 litres

1 litre is the volume of a cube of side 10cm (1 decimetre, or 1 dm),
so the volume of the suitcase is 5.0dm × 3.7dm × 2.0dm = 37 litres

Volume = V = 50*37*20 = 37,000 cm^3 = 37,000 mL
= 37 L

I know you asked about math, but "it's" is short for "it is". When you want to show the possessive form of the pronoun "it", there is no apostrophe. The word "its" means belonging to it.

"Its measurements are..."
50 cm × 37 cm × 20 cm = 37,000 cm³

1 liter = 1,000 cm³

Answer:
37 liters

A liter is 1000 cm^3. Do your own math.

Volume of your suitcase:
50 cm × 37 cm × 20 cm
= 37,000 cm^3
= 37 litres

rule
1 L = 1000 cm^3
