a large storage container in the shape of a rectangular prism has the dimensions of the following: length 16.5m width 18.2m heig
Zielflug [23.3K]

Answer:

3603 boxes.

Step-by-step explanation:

Rectangular Prism is actually a cuboid.

Volume of cuboid = length * width * height.

It is given that length = 16.5 m,  width = 18.2 m, and height = 12 m. Therefore:

Volume = 16.5 * 18.2 * 12 = 3603.6 cubic meters.

Volume is actually the capacity of the shape. If the box has the volume of 1 cubic meters, then the number of boxes that can fit in the rectangular prism will be:

Number of boxes to be fit = Volume of Large container/Volume of Small Container.

Number of boxes = 3603.6/1 = 3603 boxes.

Therefore, 3603 boxes will fit the rectangular prism and 0.6 cubic meters will be the spare space!!!

The faces of a tetrahedron die are numbered 1 to 4. If each of the 4 sides is equally likely to land down, what is the probabili
Marat540 [252]
Hello!

If there is 4 faces and 1/4 chance of any side end up face down, we just have to decrease one chance, so, the chance of  the face "2" does not end up face down is equal the sum of the chances of the others faces end up face down, so, we have: 3/4.

Can someone please help me
Bad White [126]

Answer:

<h2>L.A. = 384 cm²</h2><h2>S.A. = 640 cm²</h2>

Step-by-step explanation:

Lateral Area:

We have four congruent triangles with base b = 16cm and height h = 12cm.

The formula of an area of a traingle:

A_\triangle=\dfrac{bh}{2}

Substitute:

A_\triangle=\dfrac{(16)(12)}{2}=(8)(12)=96\ cm^2

L.A.=4A_\triangle=4(96)=384\ cm^2

Surface Area:

S.A.=B+L.A.

In the base we have the square with side s = 16cm. The formula of an area of a square:

A_\square=s^2

Substitute:

B=16^2=256\ cm^2

S.A.=256\ cm^2+384\ cm^2=640\ cm^2
