how many \dfrac13
3
1

start fraction, 1, divided by, 3, end fraction unit cubes does it take to fill the prism?

135 cubes are required to fill the prism

Solution:

Given that a rectangular prism with volume of 5 cubic units is filled with cubes with side lengths of units

Then the number of cubes required to fill the prism will be given by:

Volume of rectangular prism = 5 cubic units

Therefore number of cubes required to fill the prism are:

Therefore 135 cubes are required to fill the prism

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
