Step-by-step explanation:
The lateral surface is the sum of the areas of all the sides, or 'faces'.
The bases (the top and bottom) are <u>not </u>included.
This is a prism with triangles for bases (at each end). The sides are rectangles.
Add up the areas of the rectangles.
300 + 480 + 600 = 1380

Step-by-step explanation:
We have been given that a hiker begins in a valley at 150 feet below sea level. When the hiker reaches the highest point on the trail, he is 579 feet above sea level. We are asked to find change (in feet) in elevation of the hiker.
To find change in hiker's elevation we will subtract hiker's initial elevation from hiker's elevation at the end of trail.

We are subtracting negative 150 because at the beginning of trail hiker was 150 feet below sea level.


Therefore, the change in hiker's elevation is 729 feet.
