What is the surface area of this wedge ?
Bess [88]

Answer: 84 ft^2  

Step-by-step explanation:

The whole prism can be divided into  5 surfaces.

Two triangles and 3 rectangles.

 Find the area of each of the 5 shapes and add them together.

The triangle has a  base of 4 and a height of  3.

Area of triangle 1:    A= 4*3 * 1/2  

                               A = 6  

Area of triangle 2:     A = 4*3 * 1/2

                                   A = 6

Area of rectangle 1 :   A= 4*6

                                    A = 24

Area of rectangle 2;   A = 3*6  

                                     A = 18

Area of rectangle 3:    A= 5 *6  

                                      A = 30

Now add the areas together

    6 + 6 + 24 + 18 + 30 + =  84 ft^2

Order 130 in, 4 yd in 10 ft from greatest to least
Angelina_Jolie [31]

Answer: 4 yd, 130 in, 10ft

Step-by-step explanation:

So first you turn everything into inches

130 inches is already in inches.

4 yards = 12 ft

1ft = 12 in

12 *12 = 144 in

so 4 yards is 144 inches

10 ft = 12*10

12*10 = 120

so 10ft is 120 inches

144 inches is the greatest and 120 inches is the least.

The answer needs to be in the original form.
