butalik [34]

Answer:

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.

Please have a look at the attached photo.

My answer:

We need to find the total surface area of the building a skateboard ramp without its bottom.

The Area of the slope: 10.5*25 = 262.5 $ft^{2}$
The Area of the two triangles: 2 ( $\frac{1}{2} 7*24$ ) = 168 $ft^{2}$
The Area of the back: 10.5*7 = 73.5 $ft^{2}$

So the total surface area is: 262.5 + 168 +73.5 = 504 $ft^{2}$

Hence, the number quarts of paint will mario needs to buy is:

504/85 ≈ 6

Hope it will find you well

Which three-dimensional figure has the greatest number of faces?

Digiron [165]

Answer:

Octagonal pyramid

Step-by-step explanation:

Hexagonal Prism: 8 faces

2 hexagon bases, and 6 faces that connect each side of the bases

Octagonal pyramid: 9 faces

One octagon base, and 8 faces that meet at a point- all extending from each side of the base

Rectangular prism: 6 faces

Two rectangle bases, and 4 faces connecting each side of the bases

Pentagonal pyramid: 6 faces

One pentagon base, and 5 faces that meet at a point- all extending from each side of the base

I recommend searching for a picture of each of the figures to help you understand this.

small cubes with edge lengths of 1/4 inch will be packed into the right rectangular prism shown.( the base is 4 1/2, the width i

ss7ja [257]

General Idea:

We need to find the volume of the small cube given the side length of the small cube as 1/4 inch.

Also we need to find the volume of the right rectangular prism with the given dimension (the height is 4 1/2, the width is 5, and the length is 3 3/4).

To find the number of small cubes that are needed to completely fill the right rectangular prism, we need to divide volume of right rectangular prism by volume of each small cube.

Formula Used:

$Volume \; of \; Cube = a^3 \; \\\{where \; a \; is \; side \; length \; of \; cube\}\\\\Volume \; of \; Right \; Rectangular \; Prism=L \times W \times H\\\{Where \; L \; is \; Length, \; W \; is \; Width, \;and \; H \; is \; Height\}$

Applying the concept:

Volume of Small Cube:

$V_{cube}= (\frac{1}{4} )^3= \frac{1}{64} \; in^3\\\\V_{Prism}= 3 \frac{3}{4} \times 5 \times 4 \frac{1}{2} = \frac{15}{4} \times \frac{5}{1} \times \frac{9}{2} = \frac{675}{8} \\\\Number \; of \; small \; cubes= \frac{V_{Prism}}{V_{Cube}} = \frac{675}{8} \div \frac{1}{64} \\\\Flip \; the \; second \; fraction\; and \; multiply \; with \; the \; first \; fraction\\\\Number \; of \; small \; cubes \;= \frac{675}{8} \times \frac{64}{1} = 5400$

Conclusion:

The number of small cubes with side length as 1/4 inches that are needed to completely fill the right rectangular prism whose height is 4 1/2 inches, width is 5 inches, and length is 3 3/4 inches is <em><u>5400 </u></em>
