4) A piece of wood in the shape of a rectangular prism has dimensions of 11 cm by 5 cm by 3 cm. It has a mass of 96.4 grams Datormine its density.

density = 0.58 g/cm^3

Step-by-step explanation:

Volume of rectangular prism = L × B × H

( Where, L = length, B = width, H = height )

=》11 × 5 × 3

=》165 cubic cm

Now, we know that density =

=》

=》

density = 0.58 grams per centimeter cube

( g / cm^3)

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
