What is the surface area of this right rectangular prIsm?
uranmaximum [27]

Answer:

28

Step-by-step explanation:

To find the area of a rectangle we multiply two edges together.

since we are looking for the surface area we are actually going to be finding 6 different areas and adding them together (since there are 6 sides to a rectangle)

ok so sides 1 and 2, the edges on the left and right will be equal, and then the four sides in the middle are all going to be equal

2(1x2) + 4(3x2) = 4 + 24 = 28

Anna35 [415]

Answer:

The scale reading that the chef need to see for this spice when preparing the specialty for 43 people is 0.86.

Step-by-step explanation:

In order to find the answer, you need to multiply the amount that the chef uses per serving for the number of servings. The statement indicates that the chef uses ​one- fiftieth of an ounce of a spice per serving and this is represented as 1/50 and you have to multiply this for 43 that is the number of people.

You can find 1/50 as a decimal dividing 1 by 50:

1/50=0.02

Now, you can multiply this value for 43:

0.02=43=0.86

According to this, the answer is that the scale reading that the chef need to see for this spice when preparing the specialty for 43 people is 0.86.
