1 ft = 12 inches and 1 inch = 2.54 cm So 1 ft = (12 times 2.54) cm 600 cm = [ 600 / (12 x 2.54) ] = 19.685 ft (rounded)
The answer will vary slightly depending on assumptions: will the slabs have a space between them, and will you be cutting the slabs to fill fractions. 21 feet is equal to 14.2 of the 450 mm slabs. 19 feet is equal to 12.9 of the slabs. To complete the rectangular area, 14.2 x 12.9 = 183 slabs.
volume = length x width x height = 20 x 10 x3 = 600 cubic cm
20*30 = 600 sq cm.
140
1 mm = 0.1 cm 600 mm = 600 x .1 = 60 cm
You will need 63 44cm x 44cm slabs to cover that area.
No units are given, but a reasonable size fish tank would have those dimensions in mm, so I'll assume they should be mm: 1 litre = 1,000 cu cm 10 mm = 1 cm volume = length x width x depth = 600 mm x 1200 mm x 600 mm = (600 ÷ 10 cm) x (1200 ÷ 10 cm) x (600 ÷ 10 cm) = 60 cm x 120 cm x 60 cm = 432,000 cu cm = 432 litres. Adjust calculation as required for other units.
Assume the surface area is 600 cm2 and NOT 600 cm as stated. Suppose the side of the cube is x cm. Then the surface area is 6x2 cm So 6x2 = 600 => x2 = 100 => x = 10 cm.
20 x 30 = 600 square cm
A square slab measuring 0.6 metres all round has an area of 0.36 square metres. This means that to cover an area of 24 square metres you will need 66 slabs and 2/3 of a slab. Covering the area may be problematic if 1/3 of a slab and 2/3 of a slab become involved, of lesser fractions, depending on the exact length and width which gave the area of 24 - and if there is a pattern to maintain.

volume = length x width x height = 20 x 10 x3 = 600 cubic cm
100 centimeters per meter, so 100cm x 6 = 600 cm.
20*30 = 600 sq cm.
