What is the total surface area of the rectangular
prism represented by this net?

150.88

Step-by-step explanation:

Side lengths are 7.4 ,3.1 and 5

How i do it is do all the combinations so 7.4 x 3.1 = 22.94

5 x 3.1 = 15.5 and 7.4 x 5 = 37

then add them all up 22.94 + 15.5 = 38.44 + 37 = 75.44

Now double it since there is two heights, two lengths and two widths

75.44 x 2 = 150.88

If you think there are 4 heights and lengths and widths we already included all numbers twice so just double it

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.

square pyramid

step-by-step explanation:

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base
