Anon-standard issue u. s. federal reserve gold bar measures 7.00 x 4.625 x 2.14 inches. if gold has a density of 19.3 g/cm3 , what is the mass of a gold bar in kg and pounds?

mass is 48.1666 pound

Explanation:

given data

gold bar length L = 7 inches = 17.78 cm

gold bar width W = 4.625 inches = 11.75 cm

gold bar height H = 2.14 inches = 5.43 cm

gold density = 19.3 g/cm³

to find out

mass of gold bar

solution

we know volume of gold bar that is

volume = L×W×H    1

volume = 17.78×11.75×5.43

volume V = 1134.40 cm

now we know that

density = mass / volume    2

so put here value

19.3 = mass / 1134.40

mass = 19.3 × 1134.40

mass = 21893.92 gram

we know 1 gram = 0.0022 pound

so mass is 48.1666 pound

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
