the surface area of the prism is $234mm^2$ .

Step-by-step explanation:

Here we have , A right rectangular prism has a length of 15 millimeters, width of 3 millimeters, and height of 4 millimeters. We need to find What is the surface area of the prism . Let's find out:

We know that surface area of the prism = $2(lb+bw+wl)$ . According to question we have following parameters as :

$length = 15 mm\\width=3mm\\height=4mm$

Putting these values to find area of prism we get:

⇒ $Area = 2(lw+wh+hl)$

⇒ $Area = 2(15(3)+3(4)+4(15))$

⇒ $Area = 2(45+12+60)$

⇒ $Area = 2(117)$

⇒ $Area = 234mm^2$

Therefore , the surface area of the prism is $234mm^2$ .

Question
---------------------------------------------------------------------------------------
$12x^4(- \frac{5}{6} x^3y^2)$

---------------------------------------------------------------------------------------
Multiply the constant: 12 x (-5/6)
---------------------------------------------------------------------------------------
$-10x^4( x^3y^2)$

---------------------------------------------------------------------------------------
Multiply the x (we add the power together when we multiply)
---------------------------------------------------------------------------------------
$-10x^7y^2$

---------------------------------------------------------------------------------------
Answer: -10x⁷y²

Hi there!

1) Determine the perimeter of the square

We're given that the perimeters of the square and the rectangle are equal. Therefore, after finding the perimeter of the square, we will also know the perimeter of the rectangle.

Find the side length of the square using the area formula:

$A=l^2$ where l is the side length
