If a roasting is 600mm x 500mm how many 25cm cake time will fit on it?

So assuming that 25cm is 25 square cm because you cannot have a 2 dimentional cake so

600mm by 500mm

to find the area, multiply legnth by width

mm=milimeters

cm=centimeters

this is in mm so

1cm=10mm

1mm=1/10cm

to convert from mm to cm, you divide by 10

we must divide by 10 first

legnth = 600mm

600/10=60cm

legnth=60cm

width=500mm

500/10=50cm

width=50cm

area=60 times 50=3000 square cm or cm^2

so 3000 is the area

25 is the area of each cake

divide 3000 into 25 and find how many cakes will fit

3000/25=120

120 cakes will fit
