Answer: 12 storage cubes will fit into Melissa's crate

Step-by-step explanation:

Melissa's crate is a cuboid. Since the crate has a bottom dimension of 8 inches by 12 inches, it is assumed that the width of the cuboid (crate) is 8 inches and the length of the cuboid is 12 inches.

Since the volume = 768 cubic inches, the length = ? inches

The volume of cuboid = length × width × height

768 = 12 × 8 × h

96 × h = 768

h = 768/96

h = 8 inches

The height of the cuboid is 8 inches.

Now, since each of the cubes being stacked into the crate has a side of 4 inches, the volume of each cube is therefore:-

Volume of a cube = L^3 (since all sides of a cube is equal)

Where L = length of a side of cube

Volume = 4 × 4 × 4

Volume = 64 cubic inches.

To calculate the quantity of storage cubes that can fit into the crate, we then divide the volume of the crate by the volume of the storage cube:

= 768/64

= 12

Therefore, 12 storage cubes will fit into the crate.

Answer:

12 cubes can fit in the create.

Step-by-step explanation:

We know that the volume of a the crate is 768 in³, and the definition of the volume is:

V=A*h

Where:

  • V is the volume
  • A is the area (A=8*12 in²)
  • h is the height

So h=\frac{V}{A}=\frac{768}{12*8}=8 in    

Now, we know that the storage cube has a length of 4 in so we have a volume equal to 64 in³. Therefore we just need to divide 768 in³ by 64 in³ it is 12.

Finally, 12 cubes can fit in the create.

I hope it helps you!

1. Write the linear equation 2x – 3y = 24 slope-intercept form.
mel-nik [20]

Answer:

y=2/3x-8

Step-by-step explanation:

2x-3y=24

3y=2x-24

y=2/3x-24/3

y=2/3x-8

y=mx+b where m=slope and b=y-intercept.

Solve the system of equations using the substitution method. -x − 2y = 0 y = -8x (x, y) = ( , )
marta [7]

Answer:

= { \tt{(0, \: 0)}}

Step-by-step explanation:

Let:

{ \bf{ - x - 2y = 0 -  -  - (a)}} \\ { \bf{y =  - 8x -  -  - (b)}}

Substitute for y in equation (b) to equation (a):

{ \tt{ - x - 2( - 8x) = 0}} \\ { \tt{ - x + 16x = 0 }} \\ { \tt{x = 0}}

Also, y = 0
