Answer:
The interest is
<h2>$ 769.50</h2>
Step-by-step explanation:
Simple interest is given by

where 
P is the principal
R is the rate
T is the time given
From the question 
The principal / P = $ 5700
The rate / R = 4.5%
The time given / T = 3 years
So the interest is


We have the final answer as
I = $ 769.50

The expression of Volume in cubic meter   (8)(6)(6)+(8)(6)(4)
 (8)(6)(6)+(8)(6)(4)
The correct option is (1)
<h3>What is Volume?</h3>
Volume can also be defined as the amount of space occupied by a 3-dimensional object. The volume of a solid like a cube or a cuboid is measured by counting the number of unit cubes it contains.
Volume will be,
V= Volume of rectangular pyramid + Volume of cuboid
  
Volume of rectangular pyramid=  * base area* height
 * base area* height
                                                    =  * 6*8*(10-4)
 * 6*8*(10-4)
                                                    = * 6*8*6
 * 6*8*6
 Volume of cuboid= l*b*h
                               = 4*6*8
So, Volume   = * 6*8*6 + 4*6*8
 * 6*8*6 + 4*6*8
                      =  (8)(6)(6)+(8)(6)(4)
 (8)(6)(6)+(8)(6)(4)
So, The expression of Volume in cubic meter   (8)(6)(6)+(8)(6)(4).
 (8)(6)(6)+(8)(6)(4).

The answer is 2/8 and 4/12 because if you times the 1/4 equation by 2 you would get 2/8 and then times 1/4 by 3 then you would get 4/12
