Answer:
21 in²
Step-by-step explanation:
The net consists of a square and 4 triangles. The relevant dimensions of each are given, so the appropriate area formulas can be used.
Area of one triangle:
A = 1/2bh
A = 1/2(3 in)(2 in) = 3 in²
Area of the square:
A = s²
A = (3 in)² = 9 in²
__
Total net area (surface area of the pyramid):
square area + 4 × triangle area
9 in² + 4 × 3 in² = 21 in² . . . . surface area
Answer:
1/2
Step-by-step explanation:
1/3 divided by 2/3
1/2
No, to be similar the sides need to be proportional, in which they are not. 8/5=1.6 and 10/7=1.4.
B. Because if you add 10+9=19, that's the side of a small side, so it wouldn't make since if you chose A. right? and it can't be D. because that's too high
