to study fluctuation in leaf water potential, sample of wood were taken from 25 trees and cut in the shape of a cube. the length of the edge of one of these cubes is 3.000 centimetres. this cube has a density of 0.220 grams per cubic centimetres. what is the mass of this cube, in grams?
Answer
Explanation:
Step1: Calculate the volume of the cube
The volume formula for a cube is $V = s^3$, where $s$ is the edge - length. Given $s = 3.000$ cm, so $V=(3.000)^3=27$ $cm^3$.
Step2: Calculate the mass of the cube
The density formula is $\rho=\frac{m}{V}$, where $\rho$ is density, $m$ is mass, and $V$ is volume. Rearranging for $m$ gives $m=\rho V$. Given $\rho = 0.220$ g/cm³ and $V = 27$ $cm^3$, then $m=0.220\times27 = 5.94$ g.
Answer:
5.94 g
