188.78 L
1. Covert the sizes to cm.
1 ft=12 inches
1 inch=2.54 cm
4 ft=121.92 cm
15 inches=38.1 cm
16 inches=40.64 cm
2. Get the volume = lwh
V=(121.92 cm)(38.1 cm)(40.64 cm)
V=188 778.9773 cc
3. Convert to liters 1L=1000 cc or cubic cm
188 778.9773 cc(1L/1000 cc)= 188.78 L

1. Throw away your tape measure with inches on and get a metric only one. These are not cluttered with fractions of inches and you can measure from the left or right on both sides of the blade.
2. Measure the width & length in cm and the estimated depth of water (if you fill it right to the top, some will spill out).
3. Multiply all the numbers together. Put a decimal point 3 digits from the right (divide by 1000), or just cross out the last three numbers, if you don't need to be too accurate, and that's your answer in litres (it's also the mass of the water in kg)
It will be roughly 122cm x 38cm x 38cm = 176.168 litres
4. Estimate the volume of the fish, gravel, pirate ships etc. at 168 cc and subract it from your calculated figure.
5. Volume of water = 176 litres.

4 foot = 48 inches. Volume of tank = 48 x 16 x 15 = 11520 cubic inches. Convert to litres, to give, exactly:
188.77893120000002 litres.

Convert all sizes to metres reading across a tape with both.
Multiply Length by Breadth by Height.
Remember 1 cubic metre of water = 1 Tonne

I can't believe how many wrong answers you got. The correct answer is: 48 x 16 x 15 = 11,520 cubic inches which gives you:
188.77897728 litres.

Volume of the tank in inches:
(4ft*12)*15inches*16inches
= 11520 cubic inches
1 inch = 2.54 cm = 25.4 millimeters
Therefore
11520 cubic inches = 29260.8 cubic millileters
1000 millileters = 1 liter
Therefore
Volume of Tank = 29.26 liters

the size is roughly 122 x 38 x 40.5 cms
= 187758 ccs
approx 188 litres which will be roughly 188 kilos of water, dependant on temperature and pressure.

Another easy way to convert is to shift all to the metric system and quit using the US measures. Convert 4ft to 48in then multiply by 2.54cm/in; 15in by 2.54cm/in; 16in by 2.54cm/in... this will give you a volume in cubic centimeters which if divided by 1000 will give you the litres of the tank.

firstly, convert the lengths into cm:-
length = 121.92cm
width = 38.1cm
height = 40.64cm
now work out the volume:-
volume = 121.92 x 38.1 x 40.64 = 188778.97728 cubic cm
now since 1ml = 1 cubic cm, the total volume is :-
188778.97728 ml
i.e approx 188.78 litres

base area times height gives the volume.
Volume=w * l * h
=15 * 4 * 16
=960 inch cube
=960 * 2,54 /10 dm cube
= 243,84 litres.
