Answer 2

Answer:

cross section= 10cm²

Explanation:

given mass= 435g

density= 8.7g/cm³

length = 5cm

since mass = density × volume

therefore 435g = 8.7g/cm³ × volume

volume = 435g ÷8.7g/cm³ = 50cm³

since volume = cross section × length

therefore 50cm³= cross section × 5cm

50cm³÷5cm = cross section

therefore cross section = 10cm²
