Please solve, really easy, but I really don’t know....
PLEASE I WILL MARK YOU AS BRAINLIEST IF ANSWERED CORRECTLY!
Solve for A and B plz

A)

B)

Step-by-step explanation:

The formula for the volume of a cube is:

V =

Where;

V = Volume

a = side

Plug the information into the formula.

V =

V =

That is the volume of one cube. If all of the cubes have the same length, in order to find the volume of the whole figure, we must count how many cubes there are and multiply that number by the volume.

If I am not mistaken, I can count 10 cubes.

10 times the Volume of one cube = Volume of the solid figure.

Therefore, the volume of the solid figure is

To convert our number to scientific notation, we are going to move the decimal point to the right until we have only one non-zero digit to the left of the decimal point, and then, we are going to multiply that number by a negative power of 10 equal to the number of times we moved the decimal point to the right:

Our number is 0.000000016, so we need to move the decimal point 8 times to the right to have only one non-zero digit to the left of the decimal point (1.6). Since we moved the decimal point eight times to the right, we are going to multiply 1.6 by y a negative power of 10 equal to the number of times we moved the decimal point to the right i.e. .
So 0.000000016 expressed in scientific notation is 1.6x, or in calculator notation 1.6E-8

We can conclude that the correct answers are 1.6E-8 and 1.6 × 10-8
