Answer:

V = 9.828 * 10^7 mm^3

a= 9.828 b = 7

9,827,000 mm^3

Step-by-step explanation:

The volume of a rectangular prism is

V = l*w*h

V = 1.2 *10^3 * 3.9*10^2 * 2.1*10^2

We multiply the numbers out front and add the exponents (the powers of 10)

V = (1.2*3.9*2.1) * 10^(3+2+2)

V = 9.828 * 10^7 mm^3

Rewriting this in standard form means moving the decimal 7 places to the left. Since there is not enough places add zeros

9,827,000 mm^3
