Question

answer the questions below. give exact integer or decimal answers. be sure to include the correct units in your answers. (a) an object has a mass of 560 kg and a volume of 350 m³. what is the density of the object? density = (b) another object has a volume of 65 m³ and a density of 26 (kg)/(m³). what is the mass of the object? mass =

Explanation:

Part (a)

Step1: Recall density formula

Density formula is $\text{Density} = \frac{\text{Mass}}{\text{Volume}}$.

Step2: Substitute values

Given mass = $560\ \text{kg}$, volume = $350\ \text{m}^3$. So, $\text{Density} = \frac{560}{350}$.

Step3: Calculate the value

$\frac{560}{350} = 1.6$. The unit is $\frac{\text{kg}}{\text{m}^3}$.

Step1: Recall mass formula from density

We know that $\text{Mass} = \text{Density} \times \text{Volume}$.

Step2: Substitute values

Given density = $26\ \frac{\text{kg}}{\text{m}^3}$, volume = $65\ \text{m}^3$. So, $\text{Mass} = 26\times65$.

Step3: Calculate the value

$26\times65 = 1690$. The unit is $\text{kg}$.

Answer:

$1.6\ \frac{\text{kg}}{\text{m}^3}$
