Vanessa bakes a rectangular cake that is 9 inches wide,13 inches long and 2 inches high. She removes the cake from the pan to fr

TEA [102]

This is a rectangular cake, and there are 3 measurements, meaning that you are evidently finding volume.

Let's go back, first off, the formula for volume is...

V = L x W x H (Length, Width, Height)
Your measurements are 9 in, 13 in, 2 in.

All you need to do is follow the formula and multiply them.

9 x 2 = 18
18 x 13 = 234 $in^{2}$

Your answer is C: 234 $in^{2}$

Hope this helps!

a solid pyramid with a square base with side 12 cm and height 25 cm is made of metal. The metal is melted to form spherical ball

dangina [55]

Answer:

3 pyramids.

Step-by-step explanation:

The volume of one pyramid is 1/3 * b^2 * h

= 1/3 * 12^2 * 25

= 1200 cm^3.

The volume of one ball bearing = 4/3 * π * 0.7^3

= 1.43676 cm^3.

Therefore the volume of 2490 ball bearings = 2490 * 1 .43676

= 3577.53 cm^3.

So we need 3577.53 / 1200 = 2.98 = 3 pyramids.
