The surface area is the area of all the surfaces basically.
so the three rectangular sides are 7 by 5, which gives you 35.
There's three of them, so 105.
There are also two triangular sides that are 6 by 4.
equation to find area of triangle is b · h, which is a fancy equation for half base times height.
so base times height, 24. Half is 12.
There are two sides, so 24 units squared.
105+24 is 129.

In order to subtract fractions, you need to have like denominators, so you need to convert into an equivalent fraction with a denominator of '8'. Since 4 x 2 = 8, then you also need to multiply the numerator by the same factor: 3 x 2 = 6.
Answer:
quotient: 4x^3 -4x^2 -x +6
remainder: 3
Step-by-step explanation:
See the attached for the long division. As with any long division, at each step, the quotient term multiplies the divisor and the result is subtracted to form the new dividend.
