Given:
______________________________________________
$18.99 per 340.23 grams ;
and given:
1 gram ≈ 0.03527 oz (ounces) ;
______________________________________________
Find the unit price per OUNCE (oz).
______________________________________________
Given: $18.99 per 340.23 grams ;
Convert: "340.23 grams" to "ounces (oz)".
Given: "1 gram ≈ 0.03527 oz" ;
340.23 grams = (340.23 * 0.03527) oz. = 11.9999121 (about "12 oz.").
So, $19 / 12 oz. = ? dollars per UNIT OZ. ; =
(19/12) dollars per oz. = (19÷12) dollars per oz. = $ 1.58333 ; which corresponds to: Answer choice: [C]: $1.58 .

Answer:
The height is 2 units
Step-by-step explanation:
Find the area of the base of the square pyramid
we know that
The volume of the square pyramid is equal to

where
B is the area of the base and H is the height of the pyramid
we have


substitute in the formula and solve for B


step 2
Find the height of the square prism
we know that
The volume of the square prism is equal to

where
B is the area of the base and h is the height of the prism
we have


substitute in the formula and solve for h


We'll have this following figure drawn in the picture. Since we have an isosceles trapezoid, the diagonals are congruent. According to the conditions of the problem, these diagonals are perpendicular and then we can claim that we'll have right-isosceles triangles in this case. Indeed, ∠OBC = ∠FBD = 45°. Then, in the triangle BFD. BF=FD=23. It means the height is 23 cm. Obtaining this fact, we can easily calculate the area.
