Question
numeric 2 points the dimensions of a material are: 5.60 cm by 3.20 cm by 1.10 cm. calculate the mass of the material, in g, if the density is 7.80 g/cm³
Step1: Calcular el volumen del material
El volumen $V$ de un prisma rectangular se calcula como $V = l\times w\times h$, donde $l = 5.60$ cm, $w = 3.20$ cm y $h = 1.10$ cm. Entonces $V=5.60\times3.20\times1.10$ $V = 19.712$ $cm^{3}$.
Step2: Calcular la masa del material
La densidad $
ho$ está dada por la fórmula $
ho=\frac{m}{V}$, donde $
ho = 7.80$ g/cm³ y $V = 19.712$ cm³. Despejando $m$ (masa), tenemos $m=
ho\times V$. Entonces $m = 7.80\times19.712$ $m=153.7536$ g.
