A birthday cake measuring 60 CM by 40 cm by 15 cm is ordered for a party. If each child in the party enjoys 240 cm cube of cake and the cake is finished, how many children attend the party?​

Answer 1

Answer:

300

Step-by-step explanation:

volume of cuboid=length*breadth*height

=60*40*15=36000

volume of piece for each person=240

1 person ==240

x== 36000(Cris cross method)

x=36000/240=300

Answer 2

150 children attend the party

Step-by-step explanation:

A birthday cake measuring 60 cm by 40 cm by 15 cm

i.e length = 60 cm

breadth = 40 cm

height = 15 cm

volume of the birthday cake = length ×breadth × height

= 60 × 40 × 15

= 36000 cm³

volume of the cake piece per child = 240 cm³

number of children attend the party =  $\frac {volume of cake }{volume of piece}$

= $\frac{36000}{240}$

= 150 children

hence,

150 children attend the party
