What are the sides of a square is the area is 25cm3?
Areas are a square dimension. So I assume you meant what are the sides of a square with area 25 cm2? Area_square = side2 ⇒ side = √area = √(25 cm2) = 5 cm
What is the total surface area of a square prism which shows height 12 cm and base area 25 cm square?
The base is a square, so since it's area is 25 cm2 it's sides are 5 cm each in length. Thus, the rectangular sides of the prism have an area of 5x12 or 60 cm2. The total surface area is the sum of the 4 rectangular sides at 60 cm2 and the two square faces at 25 cm2.4*60 + 2*25 = 240 + 50 = 290 cm2
What is the greatest area for a rectangle with perimeter 20cm?
The greatest area is attained when the rectangle is, in fact, a square. Then it has sides of 5 cm and an area of 25 cm2. If you are not permitted to have a square then the answer is as close to 25 cm2 as you can get without actually getting there. So, more than 24.99, more than 24.99999 etc but never quite 25.
What is the total surface area of a square pyramid that has a base length of 14 cm and the slant length is 25 cm?
Height of side = square root of (625 cm2 + 196 cm2) = 28.65 cm Surface area of 4 sides = 4 x 28.65 cm x 14 cm = 1,604 cm2 Area of base = 196 cm2 Total surface area, including area of base, is 1,800 cm2
How can you make a rectangle with an area of 25 cm?
cm is not a unit of area, it is a unit of length. If you mean cm2, choose any measure (in cm) for the length, then divide 25 by that length to obtain the corresponding width.
