Answer 1

Answer: 76 ft²

Explanation:

Surface area for the prism = all the area's from the net added up.

Area triangle = 1/2 bh b=base, we need to find h, height=C=8

Use pythagorean to find base

c²=a²+b2

D² = C² + b²

10² = 8² + b²

b² = 100-64

b² = 36

b = 6

Area triangle = 1/2 (6)(8)

Area triangle = 24

Area of top rectangle = LW

L, length = A = 2

W, width = C = 8

Area of top rectangle = (2)(8)

Area of top rectangle = 16

Area of bottom rectangle = LW

L, length = A = 2

W, width = B = 6

Area of bottom rectangle = (2)(6)

Area of bottom rectangle = 12

Surface Area = 2(triangle) + (top rectangle) + (bottom rectangle)

Surface Area = 2(24) +16 +12

Surface Area = 48 +28

Surface Area = 76 ft²

Answer 2

Explanation:

you have one rectangle "at the base"

S = b × h = 2ft × 6ft = 12 ft²

one rectangle "at the back"

S = b × h = 2ft × 10ft = 20 ft²

one rectangle "along the length of the hypotenuse"

S = b × h = 2ft × 8ft = 16 ft²

and two triangles

S = (b × h) / 2 = (6ft × 8ft)/2 = 24 ft²

total S = 12ft²+20ft²+16ft²+24ft²+24ft² = 96 ft²
