Option B:
Surface area of the solid is 730 square millimeters.
Solution:
Area of the rectangle = length × breadth
Length of the top net = (25 + 8 + 8) mm = 41 mm
Breadth of the top net = 5 mm
Area of the Top net = 41 mm × 5 mm
= 205 square mm
Area of the second net = 25 mm × 8 mm
= 200 square mm
Area of the third net = 25 mm × 5 mm
= 125 square mm
Area of the bottom net = 25 mm × 8 mm
= 200 square mm
Surface area of the solid = 205 mm + 200 mm + 125 mm + 200 mm
= 730 square mm
Hence surface area of the solid is 730 square millimeters.
Option A is the correct answer.
X^3 = 1/8
x^3 = (1/2)^3
x = 1/2

Since the person had $408.98 to begin with and took away/withdrawal ($178.67+$100=$278.67) $278.67 and then added/deposited $214.87....
$408.98-$278.67+$214.87=$345.18
Answer:
Step-by-step explanation:
Given that a teacher gives a test to a large group of students. The results are closely approximated by a normal curve
mu =74 and sigma =8
A grade starts from 100-8 = 92nd percentile
Z score for 92nd percentile = 1.405
X score = 74+8(1.405) = 85.24
--------------------
B cut off is to next 16%
Hence C would start for scores below 100-(8+16) = 76%
76th percentile = 0.705*8+74 =79.64
