Answer:

516 cm squared

Step-by-step explanation:

To find the surface area of a rectangular prism such as this, is basically just like finding the OUTSIDE surfaces. We are looking for the "perimeter" of a 3D shape.

How do we do it?

Calculate each face of the prism by multiplying Length x Width.
Make a shortcut by combining like-figures (front of the cube and back of the cube are the same surface areas, etc.)
Make your formula

2(4 · 15) + 2(10 · 15) + 2(12 · 4)

Answer:

There would be 9 cups of sugar with 6 cups of cocoa in the cake

Step-by-step explanation:

Put the 3 cups of sugar on top and then put a line below it to make it a ratio and then put the 2 cups of cocoa powder. Multiply cups of cocoa by 3 to make 6 cups of cocoa. Then since you multiplied the bottom you also need to multiply the top by 3, so you would multiply the 3 cups of sugar by 3 to get 9 cups of sugar in his cake.

Evaluate sin(arcsin1.7)

Andrei [34K]

Recall that $\arcsin x$ is only defined for $-1\le x\le1$ , and under this condition we have that $\sin(\arcsin x)=x$ . But 1.7 > 1, so $\arcsin1.7$ is not a real number.
