Need Explanation For This Asap! &lt;3<br> 528 cm2<br> 538 cm2 <br> 558 cm2
blsea [12.9K]

Answer:

528 cm²

Step-by-step explanation:

The surface area of this prism comprises:

  • 2 congruent triangles (the bases of the prism)
  • 2 congruent rectangles (rectangle 1 and 2) - since the triangle has 2 sides of equal length
  • 1 rectangle (rectangle 3)

Area of a triangle = 1/2 × base × height

                             = 1/2 × 16 × 6

                             = 48 cm²

Area of rectangle 1 / 2 = width × length

                                     = 10 × 12

                                     = 120 cm²

Area of rectangle 3 = width × length

                                = 16 × 12

                                = 192 cm²

Total Surface Area = 2 triangles + 2 rectangles + rectangle 3

                                = (2 × 48) + (2 × 120) + 192

                                = 96 + 240 + 192

                                = 528 cm²

Which is a irrational number<br> A. 0.277277277.....<br> B.0.333....<br> C.0.7<br> D.3.14
Alecsey [184]
A) This is a repeating decimal which means it is possible to write it in the form p/q where p & q are integers and q is nonzero. So we can rule out choice A.

B) Similar to the answer choice above, we have another repeating decimal. So we can rule out choice B. 

C) This is a terminating decimal. It does not go on forever. We can write this as a fraction (0.7 = 7/10). So we can rule out choice C.

D) This is also terminating so it seems like your teacher made a typo. What I'm thinking is that the 3.14 was meant to be a decimal that goes on forever without a pattern. This is a well known number called pi. I'm assuming that's what your teacher was going for. 

So I'd go with choice D as the answer.
