Ice cream cone
How many cm2 of dough are needed to produce an ice cream cone if it is to hold 0.3 l of ice cream and its
height is to be 15 cm. Add 8% for folds.
1. Convert litres into cm3
2. Decide which data you can calculate first and from what formula.
3. Calculate the data from point 2.
4. Write the formula for calculating … and sketch the triangle from which you calculate the missing dimension.
5. Calculate the dimension from point 4.
6. Calculate how many cm2 will be needed to produce the cone (including 8% for folds).
