Could someone please answer #35 for me
katrin2010 [14]

Answer:

408

Step-by-step explanation:

Volume = length times width times height

So in this situation we can see that 17 is the length, 8 is the width, and 6 is the height

Knowing this information we can continue

If you think of a regular cube, you can split it diagonally and then it would be 2 triangles

So we can split the width, in halve which would be 4 and then apply the formula 4*6*17 and when you solve that you get 408 Now we have to split that in halve because remember it is a triangle and a triangle is halve of a square. Halve of 408 is 204.

If we repeat that prosses for the other side we will also get 204. Now we add 204+204 to get our answer 408.

Sorry is this was a little confusing but that's the best I can explain it.

Hope that helped and have a great day!

The new athletic facility on the downtown campus measures 0.74 km by 4 km. How many square
masha68 [24]

Answer:

The sports facility is 2,960,000 sq. m   in area.

Step-by-step explanation:

The dimension of the sport facility = 0.74 km by 4 km

The Length of the facility = 4 km

The width of the facility = 0.74 km

Now, 1 km = 1000 meters

⇒ 4 km = 4 x (1000) = 4000 meters

and 0.74 km = 0.74 x (1000) = 740 meters

Now, AREA OF THE RECTANGLE = LENGTH x WIDTH

So, the area of the facility = 4000 m  x 740 km

                                         =  2,960,000 sq. m

Hence, the sports facility is 2,960,000 sq. m  in area.
