4.58401 x 10^3 you move the decimal between the first two numbers
        
             
        
        
        
If I am not mistaken the inequality would be 45x is greater than or equal to y since the minimum would be 45 minutes a day.

Answer:
3. 294 m²
4. 185,856 mm²
Step-by-step explanation:
To find the surface area of any figure, you can simply find the sum of the areas of all the sides.  In question 3, the figure is a triangular prism that has two triangular bases and three rectangular sides.  The measurements for the triangles are b = 9m and h = 6m.  The formula for the area of a triangle is base times height divided by 2, or 9 x 6 = 54/2 = 27 m². However, since there are two triangular bases, the area for both is 54 m².  The measurements for the other three rectangles are given: 
7(10) + 8(10) + 9(10) = 240 m² + 54 m² = 294 m²
The surface area of a cube is much easier since all sides are equal and can be found using the formula: 
SA = 6s², where 's' represents the measure of a side. 
SA = 6(176)² = 185,856 mm²
