So, what you are supposed to find here is the surface area of this rectangular prism. So the answer is 52 units of the special reflective material is needed.
Since total surface area of a rectangular prism = 2(lb + bh + hl)
Where l = length of the ice block
b = width of the ice block
h = height of the ice block
Now total surface area for the given dimensions = 2(4×2 + 2×3 + 3×4)
= 2(8 + 6 + 12)
7.234 + 3.9 + 6.56
7.234 + 10.46
17.694 (actual)
17.69 (rounded to the hundredths place)
17.7 (rounded to the tenths place)
18 (rounded to the ones place)
Hope this helps! ;)
Answer:
B) The triangles are similar and have the same ratios for the height to the base . The slope of the line is .
Step-by-step explanation:
The triangles share the ratio , and the slope of . This narrows down the options to either A or B. But, the difference between the options are the words "similar and congruent." Congruent means that the triangles are exactly the same shape and size. Similar means that they share a shape but are different sizes. The triangles are similar.
