Question

Chef Jordan has modes for chocolate, modeled by the cylinder below. He has a rectangular block of chocolate that measures 10 cm by 12 cm by 18 cm. He melts the block of chocolate and uses it to fill the molds. How many molds can he fill completely with the melted chocolate? Use 3.14 for . Round all answers to the nearest whole number.

Answer 1

He can fill 76 molds

Explanation:

First find the volume of the rectangular block.

V = b(h)(w)

V = 10cm(12cm)(18cm)

V = 2160cm³

Now find the volume of the cylinder mold

V = πr²(h)

V = π1.5cm²(6cm)

V = 4.71cm²(6cm)

V = 28.26cm³

Now divide the volume of the rectangular block by the volume to find the number of cylinders needed.

2160cm³/28.26cm³ = 76.43 cylinders. Rounded = 76
