Need help finding the area to these 3 simple questions

A: 500

B: 750

C: 87.72

Step-by-step explanation:

to find the area of a 2D surface all we have to do is multiply the width by the height, we will use the first question as an example, just one sec AH got it

25 * 20 = x

ok so now we solve this and we will have the surface area for this shape

25 * 20 = 500

500 is our answer for the first question, a similar method can be used to find the volume of a shape, you just multiply the third dimension as well as the first two, so with that being said.. *writes more* a 10 by 5 by 20 box would look like this

10 * 20 * 5 = y

and then we just solve accordingly

10 * 20 * 5 = 1'000

so 1'000 is the volume of that box

hope this all makes sence, 'if you have any questions please leave them in the comments down below' and ill get to them as soon as i can, take care :>
