The surface area of the rectangular prism is 427 mm². The correct option is the second option 427 mm²
<h3>Calculating surface area</h3>
From the question, we are to calculate the surface area of the rectangular prism
Surface area of a rectangular prism can be calculated by using the formula,
Surface area = 2(lw + lh + wh)
Where l is the length
w is the width
and h is the height
In the given diagram,
l = 21.5 mm
w = 4 mm
h = 5 mm
Putting the parameters into the equation, we get
Surface area = 2(21.5×4 + 21.5×5 + 4×5)
Surface area = 2(86 + 107.5 + 20)
Surface area = 2 × 213.5
Surface area = 427 mm²
Hence, the surface area of the rectangular prism is 427 mm². The correct option is the second option 427 mm²

Problems:
0.5x0.5 = 0.25
0.6x0.6 = 0.36
0.1x0.5 = 0.05
1.5x0.5 = 0.75
There are many problems like that. You can do 0.2, 0.3, 0.4, 0.5, etc. multiplying another integer.
If the ratio is 1:2,
sam has three dollars.
buffy has six dollars.
we know this because the ratio is 1;2, so we can multiply sam’s amount by two, because buffy’s amount is twice sam’s amount.
ANSWER: buffy has 6 dollars!!
if you need the new ratio: 3:6
(4x3+2x+6)+(2x3-x2+2)
Final result :
6x3 - x2 + 2x + 8
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "x2" was replaced by "x^2". 2 more similar replacement(s).
Step by step solution :
Step 1 :
Equation at the end of step 1 :
(((4•(x3))+2x)+6)+((2x3-x2)+2)
Step 2 :
Equation at the end of step 2 :
((22x3 + 2x) + 6) + (2x3 - x2 + 2)
Step 3 :
Checking for a perfect cube :
3.1 6x3-x2+2x+8 is not a perfect cube
Trying to factor by pulling out :
3.2 Factoring: 6x3-x2+2x+8
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: 2x+8
Group 2: 6x3-x2
Pull out from each group separately :
Group 1: (x+4) • (2)
Group 2: (6x-1) • (x2)
