Surface area = 2(wl + hl + hw)

top section 2(5*25 + 5*25 + 5*5) = 550

lower part = 2(5*5 + 5*5 + 5*5) = 150

150 + 150 + 550 = 850

answer is A

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

nydimaria [60]

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
