20cm daftie!!
^No, 25cm² actually. All you do is multiply 5 by 5.
Then the square will have 4 equal sides of 5cm with a perimeter of 20cm and an area of 25 square cm
25 square centimetres !
1/2*5*7 = 17.5 square cm * * * * * Only if these are the shorter legs of a right angled triangle and there is no justification for making that assumption. Two sides of a triangle are not sufficient to determine its area.
The surface area is 750 cm^3
10 square cm
25 square centimeters.
Each side is 5cm
5*3 = 15 square cm
Then the square will have 4 equal sides of 5cm with a perimeter of 20cm and an area of 25 square cm
It is 25 square cm
4 x 5cm = 20cm
twenty five
25 square centimetres !
20cm/4sides = 5cm 5cm*5cm = 25cm^2
5 x 10 = 50cm2
20 cm
the surface are of a cube that is 5 cm long, wide, and high is 150 cm^2. Each side of the box is a square measuring 5cm x 5cm, so each side has an area of 25 square cm. A box has six sides, so the total surface area of all six sides is 6 x 25 square cm = 150 square cm.
