Answer:
Lewis spent £14.82.
Step-by-step explanation:
Total number of cartons of juice Lewis bought = 38
i. If 1 carton of juice = 45 p, then;
Lewis would spend = 38 x 45 p
= 1710 p
Since 100 p = £1, then;
1710 p =
= £17.10
Lewis would have spent £17.10.
ii. If 4 cartons = £1.56, then;
= 9.5
Lewis would have spent = £1.56 x 9.5
= £14.82
Given that he bought the cartons of juice for the least possible amount. Thus, Lewis spent £14.82.
The <em>approximate surface</em> areas of corresponding prisms are listed below:
The <em>surface</em> area of the each figure (), in square units, is equal to the sum of the <em>surface</em> area of the two bases (
), in square units, and the <em>surface</em> areas of the <em>lateral</em> sides (
), in square units. Since bases are <em>regular</em> polygons, <em>base surface</em> area can be determined by this expression:
(1)
Where:
The area of one lateral side is expressed by this expression:
(2)
Where <em>h</em> is the height of the rectangle, in units.
The total surface area is defined by the following formula:
(3)
Now we proceed to calculate each surface area:
<h3>Case I (<em>A = 108.136 units²</em>
<h3>Case II (<em>A = 228.631 units²</em>
<h3>Case III (<em>A = 453.874 units²</em>
The <em>approximate surface</em> areas of corresponding prisms are listed below:
