The surface area of a 8in by 4 in by 2 in closed box is: 2 x (8 in x 4 in + 4 in x 2 in + 2 in x 8 in) = 112 in2
A shape that is 4 x 4 x 2 is not a cube. The surface area of this object is 64 square units.
Base = x + 4 Altitude = 4*base = 4*(x+4) Area = 0.5*base*altitude = 0.5*(x+4)*4*(x+4) = 2*(x+4)2
1.2 Area = pi X radius^2 So set Area = 4, and figure it out: 4 = pi X radius ^2 4/pi = radius^2
Probably not. I suspect that " lateral area means the area of a horizontal section. For example, imagine a sphere of 2 metres diameter. It's lateral area is the area of a circle of two metres diameter. A = (Pi x 2 x 2)/4 = 3.14. It's surface are is (4 x PI x 2 x 2)/4 = 12.57
Area = 4 x pi x radius2.
Area of 4 in x 6 in is 24 in^2.
Area of circle = pi x radius squared where pi = 3.1416 radius = diameter/2 = 4/2 = 2 ins Area = 3.1416 x 2 x 2 sq.ins. = 12.5664 sq ins
triangle area = 1/2 x base x height height = 2 x area /base = 2 x 32/4 = 16 cm
Assuming a rectangular prism, each of the sides are represented twice. Calculate the area of each of the sides. 2 X 4 = 8 2 X 6 = 12 4 X 6 = 24 8 + 12 + 24 = 44 44 X 2 = 88 The surface area of a 6 X 4 X 2 prism is 88.
Area of circle = pi x radius squared where pi = 3.1416 radius = diameter/2 = 4/2 = 2 ins Area = 3.1416 x 2 x 2 sq.ins. = 12.5664 sq ins
Area = 1/2 (sum of bases) times height Area = (8+12)/2 x 4 Area = 10 x 4 = 40
