Question

the total surface area of a solid cube is 294cm2. find volumn of cube.​

Answer 1

Answer:

total surface area of a cube is 294 cm^2

cube have 6 equal surface

area of each surface =294/6 cm^2

=49 cm^2

side if the cube =√49 cm=7cm

volume of the cube is 7^3 cm^3

=343 cu cm

Answer 2

Answer:

T.S.A. of cube = 294 cm²

i.e., 6 xl x1 = 294. [ T.S.A. of cube = 6 x 1²]

1² = 294/6

1² = 49

1 = √49

= 7 cm

Side (1) = 7 cm

Volume of cube = 1x1xl

= 7 x 7 x 7

= 343 cm³
