Question:

Find the surface area of the space figure represented by the net

Answers

Im pretty the answer is 164 cm. not 124 cm.!!!

14 + 14 + 56 + 40 + 40 = 164

check in a calculator

D. 164 [tex]cm^{2}[/tex]

Step-by-step explanation:

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

So, the surface area of the net = area of 3 rectangles + area of 2 triangles.

Now, there are two rectangles having length 8 cm and width 5 cm.

So, the area of this rectangle = length × breadth = 8 × 5 = 40 [tex]cm^{2}[/tex]

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

So, the area of this rectangle = length × breadth = 8 × 7 = 56 [tex]cm^{2}[/tex]

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

So, area of both of these triangles = [tex]2 \times \frac{1}{2} \times b \times h[/tex] = [tex]2 \times\frac{1}{2} \times 7 \times 4[/tex] =28 [tex]cm^{2}[/tex].

Therefore, the final area of the net = 40 + 40 + 56 + 28 = 164 [tex]cm^{2}[/tex].

Is there a pic or no

The answer to your question would be second option and it is 124 cm^2.

Solution:
The surface area = area of rectangle 7*8 + area of rectangle 5*8 + two times the area of one triangle
area of rectangle 7*8 = 56 cm²area of rectangle 5*8 = 40 cm² area of one triangle = 0.5 * 7 * 4 = 14 cm²
Total area = 56 + 40 + 2*14 = 124 cm²

The surface area = area of rectangle 7*8 + area of rectangle 5*8 + two times the area of one triangle

area of rectangle 7*8 = 56 cm²
area of rectangle 5*8 = 40 cm²
area of one triangle = 0.5 * 7 * 4 = 14 cm²

Total area = 56 + 40 + 2*14 = 124 cm²

The correct choice is the second.

The surface 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 Inches
this is what i came up with

There isnt enough information on this question, wheres the figure and the answers
