Answer:

350.82

Step-by-step explanation:

To find the surface area, you must add up all of the areas of each shape of the prism in order to get the sum surface area.

The rectangle's area (lw):

7.21*14=100.94

The triangle's area (\frac{1}{2}bh):

\frac{1}{2} (6)(8)

\frac{1}{2} (48)=24

Now add up all the sides. (3 Rectangles, 2 Triangles.)

100.94 + 100.94 + 100.94 + 24 + 24

=350.82

The total surface area is 350.82 cm squared.

A pilot of a helicopter plans to release a bucket of water on a forest fire. The height y in feet of water t seconds after its r
frosja888 [35]
You’re gonna have to use the quadratic formula here and a bit of thinking. We know y is height, and once it touches the ground, it will be 0.

(-b +- sqrt b^2 - 4ac)/2a
2 +- sqrt(4 + 48(400))/-32
(2 +- 138.58)/-32
We don’t want a negative time because it’ll make no sense. So do subtraction

(2-138.58)/-32 = 4.27 seconds aka 4.3 seconds
