Find the surface area of the prism.

2880

Step-by-step explanation:

The base is made up of two triangles and a square, if that makes sense. Finding the area of a triangle is (base x height)/2.  

The base of the tiny triangle is 4 because there is 8 inches extra to the 10 inch square. 10 x 4 = 40.

Now we have a 10 by 10 square: 10 x 10 = 100.

So, the area of the trapezoid is 140. There are two trapezoids in this prism, so both bases are 280.

The surface area of the sides are solved by 12 x 50 = 600. Together, the sides equal 1200.

The top is solved by 10 x 50 = 500.

The bottom is solved by 18 x 50 = 900.

Add them all together: 280 + 1200 + 500 + 900 = 2,880

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
