Make it a mixed number 1 1/4
Answer:
90 sq inches
Step-by-step explanation:
The lateral area is the side area of the pyramid. In this case, there are 3 sides because the base is a triangle. Since the base is an equilateral triangle, all sides are of equal dimensions. So, the sides of the pyramid are also all of the same size, area.
We then just have to figure out the area of one of the side triangles, then multiply it by 3 to get the total lateral area of that pyramid.
We know how to calculate the area of a triangle: A = (b * h)/2
In this case, b = 5 in, h = 12 in. So,
TA = (5 * 12)/2 = 60 / 2 = 30
Each side triangle has an area of 30 sq inches.
LA = 3 * TA (since there are 3 sides)
LA = 3 * 30 = 90 sq inches
Answer:
<BCF is the other alternate exterior angle.

If you can, let me know if this is correct. :)
Answer
v = 1000 cubic cm
Step-by-step explanation:
The formula for Volume of Cube is V = 
in this case the sides are 10 cm so we plug in the numbers
v = 
v = 1000 cubic cm
