Answer:

294 in.²

Step-by-step explanation:

I believe this figure is a rectangular prism.

------------------------------------------------------------------------------------

Explain:

To find the surface area of a rectangular prism, use this formula:

$SA=2lw+2lh+2wh$

$SA=2(lw+lh+wh)$

$l-length$

$w-width$

$h-height$

A phrase I use to help remember this formula is:

LISA WILSON LOST HER WITCH HAT TWICE (2)

------------------------------------------------------------------------------------

Solve:

The length of this rectangular prism is 9 in.

This width is 10 in.

The height is 3 in.

Now, I will plug the numbers into the first formula.

$SA=(2*9*10)+(2*9*3)+(2*10*3)=294 in.^2$

------------------------------------------------------------------------------------

Conclude:

I, therefore, believe the area of this rectangular prism is 294 in.²

leonid [27]

Answer:

2 hours

Step-by-step explanation:

The question is asking us to get the meeting point of the two and at what time would they arrive here given their individual speeds. Now what needs to be done here is first add their average speeds.

The total average speed = 325 + 25 = 350km/h

Now the distance the helicopter would have traveled would be ; 325/350 * 700 = 650km

The remaining distance left for the boat would be 700 - 650 = 50km

Now the time taken for this would be 650/325 or 50/25 = 2hours
