Answer:
Total surface area : 207cm²
Volume : 550.8³
Step-by-step explanation:
Surface area, first need to work out the area of each face.
A box is symmetrical so some faces will be the same.
Area = Base × Height
Top/bottom : 9 × 6 = 54cm²
side/side = 6 × 10.2 = 61.2cm²
Front/Back = 9 × 10.2 = 91.8cm²
Add then all together
54 + 61.2 + 91.8 = 207cm²
Volume = base × height × width
9 × 6 × 10.2 =550.8cm³
Answer:
47 rounds and Eve wins.
Step-by-step explanation:
If read right, the highest player, (player with the most tokens) has to lose 3 tokens each round, so starting off with Evelyn, 17 - 3 = 14, and the other two each have +1 added to them, so, E=14, A=17 V=16, now subtract three from A (Amelia) and don't forget that one token is always being discarded each round. So the toal number of tokens at the start was 48, (17 + 16 + 15) so right now the total tokens should be 47, which it is. now starting the second round, A gives up 3 tokens so, 17 -3, again equals 14 and each of the two other players get one token, so E=15, A=14 V=17. Now you know the general trend, so we can figure this out seeing that after each round the number of tokens decrease by one, so there will be a round till all tokens are out except one, so there will be 47 rounds and since E started with the highest number they will win.
