How many cubes with side lengths of 1/4 does it take to fill the prism?​
SCORPION-xisa [38]

Answer:

\large\boxed{224\ cubes}

Step-by-step explanation:

\bold{METHOD\ 1}\\\\\text{Calculate the volume of a prism:}\\\\V_{p}=(2)\left(\dfrac{7}{4}\right)(1)=3.5\ cm^3\\\\\text{Calculate the volume of a cube:}\\\\V_c=\left(\dfrac{1}{4}\right)^3=\dfrac{1}{64}\ cm^3\\\\\text{Calculate how many times the volume of the prism is greater}\\\text{than the volume of the cube:}\\\\\dfrac{V_p}{V_c}=\dfrac{3.5}{\frac{1}{64}}=3.5\cdot64=224

\bold{METHOD\ 2}\\\\2cm:\dfrac{1}{4}cm=2\cdot4=8\\\\\dfrac{7}{4}cm:\dfrac{1}{4}cm=\dfrac{7}{4}\cdot\dfrac{4}{1}=7\\\\1cm:\dfrac{1}{4}cm=1\cdot4=4\\\\8\cdot7\cdot4=224\ (cubes)

What are the zeros of the polynomial function?
Nesterboy [21]
It won't be 0 because f(0) = 300

AS the last term is 300  the zeroes could possibly be  4  of the  following possibilities  +/-1 , +/-3 , +/- 10  ( The Rational Roots Theorem)

f(3) =  3^4 - 2(3)^3 - 103(3)^2 + 209(3) + 300  = 0

so 3 is one zero  

f(10), f(-10) and f(-1)  are also = zero 

so the list is  -10, -1, 3, 10 answer
