We have the rectangular prisms.
The formula of a volume of a rectangular prism is:
l - length
w - width
h - height
==========================================
Look at the picture.
a.
Two congruent rectangular prisms 14cm × 3cm × 5cm.
b.
One rectangular prism 15in × 4in × 6in and next 7in × 4in × 3in:
c.
One rectangular prism 10cm × 3cm × 2cm and next 4cm × 3cm × 4cm:
d.

The answer is below
Step-by-step explanation:
a) Cost of hiring the bicycle for 14 days is:
Cost = 65 * 14 days + 44 = 954 riyals
b) The number of days the bicycle is hired is to be the same as the number of days the bicycle is to be hired. Let us assume that the bicycle and helmet is to be hired for x days, hence:
Cost of bicycle = 65 * x + 14 = 65x + 44
Cost of helmet = 12.5 * x = 12.5x
Total cost = 65x + 44 + 12.5x = 77.5x + 44
Since 750 riyals is available, hence:
750 = 77.5x + 44
77.5x = 706
x = 9.11
Therefore the maximum number of days is 11. The total cost for 11 days is:
Total cost = 77.5(9) + 44 = 741.5 riyals
Money not spent = 750 riyals - 741.5 riyals = 8.5 riyals
