Question

Please guys help me to solve this problem❤​

Answer 1

Step-by-step explanation:

Volume, V = l * b * h

Given, l = 40mm, b = 25mm and h = 15mm

V = 40mm * 25mm * 15 mm = 15000 mm³ = 15000 * 0.1 cm³ = 1500 cm³

Density, D = mass / volume

Given,

D = (9 g/cm³)

9g/cm³ = mass/1500cm³

mass = 9g/cm³ * 1500cm³

mass = 13500 g
