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.
Simple interest is $ 9
<em><u>Solution:</u></em>
Given that,
P = $ 400
T = 0.25 years
<em><u>The formula for simple interest is:</u></em>
Where,
I is the simple interest earned
R is the rate of interest in decimal
T is the number of years
<em><u>Substituting the values we get,</u></em>
Thus simple interest is $ 9
