Let’s start with the ice cream cone. To find the volume of the ice cream “ball” on top of the cone, we need to know the volume of a sphere.

### Formula for volume of sphere

**= 43 π r**^{3}

Where r is the radius of the sphere.

If the radius of the ice cream ball is 3cm,

Volume of ice cream “ball”

= 43 π r^{3}

= 43 (3.142) (3)^{3}

= 113.11 cm^{3}

Volume of ice cream squashed inside cone

= 0.5 x 113.11

= 56.56 cm^{3}

Total volume of ice cream in ice cream cone

= 113.11 + 56.56

= 169.67 cm^{3}

To find the volume of the ice cream inside the bread, we need to find the volume of a cuboid.

### Formula for volume of cuboid

**= length (l) x breadth (b) x height (h)**

If we measure the ice cream inside the bread, and l = 10cm, b = 5cm, h = 3.5cm.

Volume of ice cream in bread

= l x b x h

= 10 x 5 x 3.5

= 175 cm^{3}

So in this case, the volume of the ice cream in bread is slightly more than that of the ice cream cone. If the *kiasu* auntie wants to get more value for money, she should get the ice cream in bread.

Try it with your own ice cream, or use the formulas to compare the volumes of your other food!
