Question

The csa of cube is 576 cm². Find its tsa

Answer 1

Answer:864m^2

Step-by-step explanation:

we know that curved surface area of a cube =4a^2       (a represents side )

so,

     put it as -    4a^2=576

                          a^2=576/4

                          a^2=144

                          a= √144

                          a=12

now,  put the formula of total surface area

⇒ 6a^2

∴ 6 × 12 ×12

= 6×144

=864cm^2
