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

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
