Answer:
6 ft
Step-by-step explanation:
A=1/2bh. To find the area of the triangle, we subtract the area of the rectangle from the total. Which would be 108 - (12x6) = 36. Now we have the area. So, 36 = 1/2bh. "b", the base is 12. So we solve for h. h = (36x2)/12 or h = 36/6, which both equal 6.
<h3> a=10 l=14</h3><h3>total surface area of square pyramid </h3><h2> = a^+2al</h2><h3> =(10)^+2(10)(14)</h3><h3> =100+20(14)</h3><h3> =100+280</h3><h3> =380 cm^</h3>
<h3> last option is the correct one</h3>
Answer:
Step-by-step explanation:
I just need some points
Volume is Length x width x height divided by 3. You have the length and the width. which equals 24. (6x4). The volume that is present is 72... the last thing you do in the equation is divide by three so multiply 72 by 3 and get 216. This is the LxWxH. Like I said before you have the L and the W, which is 24. You would divide 24 from 216. The Height is 9cm.
