1. an asphalt block has a mass of 90 kg and a volume of 0.075 m. determines the density of the asphalt.

2. an aluminum sheet is 35 cm wide, 11 dm long and 15 mm thick. to. express these dimensions in meters b. determines the volume and mass of the slab in units of the s. i. (aluminum density = 2700 kg / m³)

1. Density = 1200[kg/m^3]; 2. Volume= 0.005775[m^3], mass= 15.59[kg]

Explanation:

1. We know that the density is defined by the following expression.

2. First we need to convert the units to meters.

wide = 35[cm] = 35/100 = 0.35[m]

long = 11 [dm] =  11 decimeters = 11/10 = 1.1[m]

Thick = 15[mm] = 15/1000 = 0.015[m]

Now we can find the density using the expression for the density.

nah.   i'm just sleepy.

the closer the planet is to the sun, the larger the gravity
