9 sq cm
Assuming you mean 3 cm per edge.1 side = 3 x 3 = 9 sq cm.6 sides total = 9 x 6 = 54 sq cm.
Assuming external area is the surface area. 2 x 6 x 4 = 48 sq cm (top and bottom area) 2 x 6 x 4 = 48 sq cm (two sides) 2 x 4 x 4 = 16 sq cm (two ends) 48 + 48 + 16 = 112 square centimetres is the total surface area.
Area = 0.5*(9 + 3)*11 = 0.5*12*11 = 66 sq cm
1 sq in = 6.452 sq cm
96 sq. cm
3 cm * 2 cm = 3*2 sq cm = 6 sq cm.
yeah. a 3cm by 3cm square.
9 sq cm
For an area measuring 4cm long and 3cm wide, the area is equal to 3cm x 4cm = 12 square cm. The perimeter is simply the sum of all the sides, so is equal to 4+4+3+3 = 14cm.
The area is 9 sq. cm. or 1.395 sq. inches. Do your homework yourself
You would need two 3 cm squares and two 2 cm squares to get a total area of 35 sq cm. A 3 cm square has an area of 9 sq cm and a 2 cm square has an area of 4 sq cm.
Assuming you mean 3 cm per edge.1 side = 3 x 3 = 9 sq cm.6 sides total = 9 x 6 = 54 sq cm.
The area of rectangle is : 24.0
4 * 7 = 28 28/2 = 14 sq cm
36 cm2 Area of a rectangle is length times width, so you would multipy 12cm by 3 cm to get 36 sq. (squared) cm.
Assuming external area is the surface area. 2 x 6 x 4 = 48 sq cm (top and bottom area) 2 x 6 x 4 = 48 sq cm (two sides) 2 x 4 x 4 = 16 sq cm (two ends) 48 + 48 + 16 = 112 square centimetres is the total surface area.
