What is the surface area of the jewelry box? And an explanation too, but if not, it’s alright!

400

Step-by-step explanation:

The surface area is found when adding the areas of all the squares in the prism. 5x10=50, and we have that square twice, so 100. Again, 5x10=50, and we have that twice, so another 100. Then, 10x10, which is 00, and we have two of those, so 200. 100+100+200=400

Hope that helped, have a nice day!

A. 400cm²

Step-by-step explanation:

The jewelry box is a rectangular prism.

Formula for surface area of a rectangular prism:

A = 2(w*l+h*l+h*w)

Plug in the numbers:

A = 2(10*10+5*10+5*10)

A = 400
