Answer:
1. 6 2. 12 3. 96 and 4.108
Explanation:
The area of each triangular base is:
A = 1/2(b)(h) A = 1/2(4)(3)
A = 6 in.2
There are two bases, so total base area is 12 in.2.
The lateral area is:
A = 8(4) + 8(3) + 8(5)
A = 96 in.2
The total surface area is 108 in.2.
Hope this helps, i got them all right but let me know if one is wrong, lol
