Question

Please help if you know how to do this, show an explanation please

Answer 1

a. 8, 3, 6, 10

b: 220

Explanation:

surface area = bh + (b1 + b2 + b3) L

6(8) + (6+8+3) x 10

48 + (17)(10)

48 + 170 = 220

Answer 2

96 ft²

Explanation:

Surface area of triangular prism:

A = 8 ft

B = 2 ft

C = 6 ft

D = 10 ft

`\boxed{\bf Surface \ area \ of \ right \ triangular \ prism = (perimeter \ of \ triangle)*B + C*A }`

= (A + C + D)* B + C*A

= (8 + 6 + 10)*2 + 6*8

= 24*2 + 48

= 48 + 48

= 96 ft²
