Answer:

There are 12 pentapods and 8 Tripods, which in total add up to 84 feet.

Step-by-step explanation:

Given that both the Tripods and the Pentapods have, at least, 3 feet (the Pentapods have 5), and that in total between both groups they add 20 heads and 84 feet, the following logical reasoning can be made:

If there are 20 heads, there are 20 Martians in all. Each of them has, at least, 3 feet, with which in principle the 20 Martians would add up to a total of 60 feet (20 x 3). Therefore, there is a surplus of 24 feet (84 - 60).

If the Pentapods have 2 feet more than the Tripods, the number of Pentapods in the total Martians is determined by that difference. Thus, if there are 24 feet left, there are 12 Pentapods (24/2).

Therefore, in the group of Martians there are 12 pentapods (12 x 5 = 60) and 8 Tripods (8 x 3 = 24), which in total add up to 84 feet (60 + 24).

Step-by-step explanation:

In order to find the amount of film needed, we have to find the surface area of this cuboid.

  • Formula to Find Surface Area of Cuboid: 2(wl+hl+hw), where w = width, l = length, and h = height.

Now, let's solve!

  • 2(36*25+20*25+20*36)  
  • 2(900+500+720)
  • 2(2120)
  • 4240

Therefore, the answer is 4240 inches².
