Question

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

Answer 1

Answer:

B. 263 cm²

Step-by-step explanation:

Surface area of the figure represented by the net = area of all parts of the net which consists of 3 rectangles and 2 triangles

✔️Area of the first two equal rectangles = 2(L*W)

L = 12 cm

W = 6 cm

Area of the first two equal rectangles = 2(12*6)

= 144 cm²

✔️Area of the third rectangle = L*W

L = 12 cm

W = 7 cm

Area = 12*7

= 84 cm²

✔️Area of the two equal triangles = 2(½*b*h) = b*h

b = 7 cm

h = 5 cm

Area = 7*5

= 35 cm²

✔️Surface area of the space figure = 144 + 84 + 35

= 263 cm²
