a rectangular prism measures 8 inches in width, 12 inches in length, and 4 inches in height. what is the surface area of the pri

laiz [17]

For this case we have that the surface area of the prism is given by:

$SA = A_ {l} + 2B$

Where:

$A_{l}$ : Is the lateral area

B: It is the area of the base

$A_ {l} = P.h$

Where:

Q: It is the perimeter of the base

h: It's the height

$A_ {l} = 40 * 4\\A_ {l} = 160 \ in ^ 2$

On the other hand:

$B = 12 * 8\\B = 96 \ in ^ 2$

So, we have:

$SA = A_ {l} + 2B\\SA = 160 \ in ^ 2 + 2 * 96 \ in ^ 2\\SA = 352 \ in ^ 2$

Answer:

$SA = 352 \ in ^ 2$

Elanso [62]

Answer:

$\large\boxed{(5x^3)(2x)^3=40x^6}$

Step-by-step explanation:

$(5x^3)(2x)^3\qquad\text{use}\ (ab)^n=a^nb^n\\\\(5x^3)(2^3x^3)=(5x^3)(8x^3)\qquad\text{use commutative law}\\\\=(5\cdot8)(x^3x^3)\qquad\text{use}\ a^na^m=a^{n+m}\\\\=40x^{3+3}=40x^6$
