I think it is 280 cubic inches: the triangle would be the base, so area would be 1/2(7x10)= 35
Take that area times the height of 8 and you get 280.
The scientific notation of 6.3 is written as 6.3 × 10^0; option A
<h3>Scientific notation</h3>
- The decimal points should be moved between the first digit and the next digit.
- When moving decimal point to the left in scientific notation; it is negative, that is, -
- When moving decimal point to the right in scientific notation; it is positive, that is, +
Therefore, since there are only two significant number in 6.3, the decimal point can not be moved.

= 6.3 × 10^0

The function of the trapezoid area is:
A(x)=(B+b)*h/2
Where B and b are the bases and h is the height.
With the given data: h=10 B and b =7 and x (it may vary which one is bigger)
-----------
So that function becomes:
A(x)=(7+x)*10/2
A(x)=(7+x)*5
----------
So if you want the inverse function, you have to operate to find x:
A(x)/5=7+x
A(x)/5-7=x
----------
So the new function is:
x(A)=A/5-7
Answer:x=24
Step-by-step explanation:x/2-8=4
Add 8 to both sides
x/2=12
Multiply each side by 2
x=24
