The surface ar area is 320 inches, (12 x 4) x 2 = 96 ( 4 x 6) x 2 = 48 ( 4 x 4) x 2 = 32 ( 6 x 12) x 2 = 144 + 320 Inchesthis is what i came up v

The surface area = area the rectangle 7*8 + area the rectangle 5*8 + 2 times the area that one trianglearea of rectangle 7*8 = 56 cm²area of rectangle 5*8 = 40 cm² area that one triangle = 0.5 * 7 * 4 = 14 cm²Total area = 56 + 40 + 2*14 = 124 cm²The correct selection is the second.

The answer to your inquiry would be 2nd option and also it is 124 cm^2.Solution:The surface ar area = area the rectangle 7*8 + area that rectangle 5*8 + 2 times the area of one trianglearea the rectangle 7*8 = 56 cm²area of rectangle 5*8 = 40 cm² area of one triangle = 0.5 * 7 * 4 = 14 cm²Total area = 56 + 40 + 2*14 = 124 cm²


D. 164

Step-by-step explanation:

We have that the net includes three rectangles and also two triangles.

You are watching: Find the surface area of the space figure represented by the net.

So, the surface ar area that the network = area the 3 rectangles + area of 2 triangles.

Now, there space two rectangles having actually length 8 cm and also width 5 cm.

So, the area that this rectangle = length × breadth = 8 × 5 = 40

Also, one rectangle has length 8 cm and width 7 cm.

So, the area of this rectangle = size × breadth = 8 × 7 = 56

Now, as there are two triangles having base length 7 cm and also height 4 cm.

So, area that both of these triangles =

*
=
*
=28 .

Therefore, the final area that the net = 40 + 40 + 56 + 28 = 164 .

Im nice the answer is 164 cm. Not 124 cm.!!!

14 + 14 + 56 + 40 + 40 = 164
