Answer:

Step-by-step explanation:

Δ = 4^{2}  - 4 * 4 * (-63)  =  16 + 16 * 63 = 16 * (1 + 63) = 16 * 64

VΔ = 4 *  8 = 32

a = (- 4 ± 32) * \frac{1}{8}

Pleaseeeee helppppDetermine how many actual fish food boxes fit in the shipping box. Show your work. Find the volume of the ship
Alex Ar [27]

Shipping box is a cube, with units

Fish food is an unitary cube, that means have x,y,z measures the same

Shipping box is a parallelepip box. Rectangular

Volume of shipping box is found by formula

V = X•Y•Z

X = 3ft, Y=3 3/4 ft, Z=3 1/4 ft

then V = (3•3+ 3•3/4)•(3+1/4) = (11 +1/4)• (3+1/4) = 33 + 11/4 + 3/4 + 1/16

V = 33 + 2 + 3/4+ 3/4 +1/16 = 35 + 25/16 = 34+ 9/16

Now, find volume using packing cubes

How many fish food boxes fit

In X direction it fits 3/(1/4) = 12

In Y direction it fits (3+3/4)/(1/4)= 15

In Z direction it fits (3+1/4)/(1/4) = 10

Now then multiply 12x15x10= 1800 fish boxes fit in larger box
