Answer:
the height of the cross section is 3 feet
Step-by-step explanation:
The computation of the height of the cross section is shown below:
Area = 1 ÷ 2 × (a + b) × h
39 = 1 ÷ 2 × (20 + 6) × h
39 = 1 ÷2 × 26 × h
39 = 26 ÷ 2 × h
39 = 13 × h
h = 39 ÷ 13
= 3 feet
hence, the height of the cross section is 3 feet
Answer:
Step-by-step explanation:
In order to find the square root, we must find a number that when multiplied by itself one time, it produces the number under consideration.
In the case of 64, the square root is 8 because 8 multiplied once by itself is 64.
However, when finding the cube root, the root must multiply by itself two times and make the number.
In the case of 64, 4 multiplied by itself two times is 64.
