Question

the base Dimensions of a rectangular box are 1.5×10 to the second power centimeters by 4.3×10 to the first power centimeters find the base area of the box right answer and say scientific notation and round coefficients to the nearest

Answer 1

Answer:

$Area = 6.5 * 10^3cm^2$ or $Area = 6.5E3\ cm^2$

Step-by-step explanation:

Given

$Width = 1.5 * 10^2cm$

$Length = 4.3 * 10^1cm$

Required

Determine the Area

The base area is calculated as:

$Area = Length * Width$

$Area = 1.5 * 10^2cm * 4.3 * 10^1 cm$

Reorder the expression

$Area = 1.5 * 4.3 * 10^1 cm* 10^2cm$

$Area = 6.45 * 10^1 cm* 10^2cm$

Apply law of indices

$Area = 6.45 * 10^{1+2}cm^2$

$Area = 6.45 * 10^3cm^2$

Approximate

$Area = 6.5 * 10^3cm^2$

or

$Area = 6.5E3\ cm^2$
