Question

Marcus found a toy that is in the shape of a rectangular pyramid and is made out of plastic. The rectangular base has a length of 4 cm and a width of 5 cm. The height of the pyramid is 6 cm. Marcus weighs the toy and finds that it is 25 grams. Find the density of the toy.(1 point)

Answer 1

Volume = (1/3)·(base area)·height = (1/3)·(4·5)·6 = 40 cm³.
Density = mass/volume = 25 g / 40 cm³ = 0.625 g/cm³ ( = 5/8 g/cm³).
