The questions or computes to do are:

<span>a- a massa, em kg, de cada placa de alumínio;

b- a quantidade mínima de viagens necessárias para que apenas um veículo de transporte entregue o material solicitado ao cliente.

Dado: densidade do alumínio = 2,7 g/cm3

Answer:

a) mass in kg of every aluminum plate

Dimensions of every aluminum plate: </span>
<span>2 M X 50 Cm X 2cm

Volume: 200 cm * 50 cm * 2 cm = 20,000 cm^3

Mass:

density = mass / volume => mass = density * volume = 2.7 g/cm^3 * 20,000 cm^3 = 54,000 g = 54 kg.

Answer: the mass of everyplate of aluminum is 54 kg.

b) number of travels required for one truck deliver all the material:

number of travels = amount requested / amount that a truck can deliver in one travel.

amount requested: 100 plates

mass of 100 plates = 100 plates * 54 kg / plate = 5,400 kg

limit of transport per travel: 3 tons = 3,000 kg

number of travels = 5,400 kg / 3,000 kg/travel = 1.8 travels => 2 travels.

Answer: at least 2 travels.
