Question

The surface area of a jumbo size Rubik’s cube is 294in2. Find the lateral edge

Answer 1

7

Explanation:

294/6 = 49

square root of 49 is 7

Answer 2

The lateral edge is
`7\ in`

Explanation:

we know that

The surface area of a cube is equal to

`SA=6b^(2)`

where

b is the length side of the cube

we have

`SA=294\ in^(2)`

substitute in the formula and solve for b

`294=6b^(2)`

`b^(2)=294/6`

`b^(2)=49`

`b=7\ in`
