Which measurements are needed in order to calculate the density of a given object?

A. Length and width

B. Mass and weight

C. Volume and temperature

D. Mass and volume

D. mass and volume are needed to calculate an object's density.

Solution:

for calculating the density of any given object we need mass of that object and the volume of that object.

because density is defined as A material's density is defined as its mass per unit volume. It is, essentially, a measurement of how tightly matter is crammed together.

ρ = m / v

therefore the answer is D.
