Three cubes, each of edge 2cm long are placed together as shown in
figure. Find the surface area of the
cuboid so formed.​

56cm²

Step-by-step explanation:

Surface Area = Number of sides exposed × s²

Number of Sides Exposed

= 14

= 14 × 2²

= 56cm²

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
