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

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%
