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

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
