Find A, B and C
Rearrange the expression
To do this, we simply compare the expressions on both sides of the equation.
So, we have:
--- (1)
--- (2)
--- (3)
Divide both sides by x² in (1)
Divide both sides by x in (2)
Substitute 2 for A.
Make B the subject
Substitute 2 for A and -1 for B in (3)
Make C the subject
Hi there!
We can begin by finding the area of the base in order to solve for the volume.
Use the formula for the area of a trapezoid:
A = 1/2(b1 + b2)h
Substitute the given values:
A = 1/2(10 + 6)5
A = 1/2(16)5
A = 40 cm²
Multiply by the depth of the prism to solve for the volume:
40 × 8 = 320 cm³
