Question

A. Consider a metal bar with dimensions of l = 3.89 cm, w = 5.80 cm, and h = 1.00 cm. Calculate the

volume of the bar (cm³)

B. The bar above has a mass of 48.1510 g. Calculate the density of the metal bar.

Answer 1

• A. Volume = 22.562 cm³
• B. Density = 2.134 g/ cm³

Step-by-step explanation:

A. Consider a metal bar with dimensions of l = 3.89 cm, w = 5.80 cm, and h = 1.00 cm

Volume is calculated by the product of length, width and height.

`\longrightarrow\sf Volume = lbh`

plugging the values,

`\longrightarrow \sf Volume = 3.89 * 5.90 * 1`

`{\longrightarrow{\pink{\sf{ Volume = 22.562 cm^3}}}}`

Hence the volume of the bar is 22.562 cm³.

B. The bar above has a mass of 48.1510 g.

Density is calculated by :

`\sf \longrightarrow Density = (Mass)/(Volume)`

Plugging the values,

`\longrightarrow \sf Density = (48.1510)/(22.562)`

`{\longrightarrow{\pink{\sf{ Density \approx 2.134 g/ cm^3}}}}`

Hence the density of the metal bar is 2.134 g/ cm^3
