cm2
2. The Volume is equal to
cm3

1. User Answers HomertheGenius
Lateral area: AL = 4 * s * h
624 = 4 * s * 13
624 = 52 s
s = 624 : 52
s = 12 cm
The surface area of the prism:
A = 2 ·12² + 624
A = 2 · 144 + 624 = 288 + 624 =912 cm²
The volume:
V = a² · h = 12² · 13 = 144 · 13 = 1,872 cm³
Answer:
1. The surface area is equal to 912 cm².
2. The volume is equal to 1,872 cm³.

A regular quadrilateral prism has 4 lateral sides, all congruent. The figures are: Surface area of the prism = 7106 sq. cm., Volume of the prism = 29952 cubic cm.
How to find volume of a right prism?
Volume of a right prism = Bh cubic units, where B is the Base's area and h is its height.
Since a regular quadrilateral prism has 4 congruent lateral sides, its lateral surface area is 4 times 624 = 2496 sq. cm.
Let its base area be B. Since the prism has got 13 inch height, it is one of the side of the lateral rectangles.
Since area of rectangle = product of two adjacent sides' lengths
624 = x times 13, x = 48 cms
This x is side of the base of that prism. Know that in a regular quadrilateral prism, due to symmetry(regularity), there is base as a square. Its side length is another side of those lateral rectangles as one side is used as height, thus, base square's side length = x = 48 cms.
Base area = B = square of 48 = 2304 sq. cm.
Thus,
Total surface area of prism = 2 times base + lateral area( as top + bottom + lateral sides make up the surface of that prism, and top is symmetric to bottom due to prism being regular)
Total surface area = 4608 + 2496 = 7106 sq. cm.
Volume of prism = B times h = 2304 times 13 = 29952 cubic cm.
Thus,
The figures are:
 Surface area of the prism = 7106 sq. cm.,
 Volume of the prism = 29952 cubic cm.
