Answer:
160 in^2.
Step-by-step explanation:
I guess this is a prism with 6 faces so the surface area is:
2 * 8 * 4 + 2 * 8*4 + 2*4*4
= 64 + 64 + 32
= 160 in^2.
Answer:
A = 15x^2 +11x+4
Step-by-step explanation:
can we assume you want the area...
A = 1/2 (B1+B2) h
A = 1/2(10x +4)(3x+2)
A= 1/2(30x^2 +22x+8)
A = 15x^2 +11x+4
Dear Mathproblemshurt, to be honest, you never really needed the number of websites in the world. It is for the fact that it asked for the percent of inactive websites and they gave you the fraction of inactive websites. Just do 2/3 to get 33.3%.
