Question

The total surface area of a cube of length 'a' open
at one end is​

Answer 1

${\huge{\red{\boxed{\mathbb{\blue{\underline{\blue{A}{\red{N}{\pink{S}{\orange{W}{\red{E}{\purple{R} }}}}}}}}}}}}$

5a²

If 'a' is the side of cube.

Step-by-step explanation:

We know that a cube have six surface.

If the length of one side is'a'.

Therefore total surface = 6a²

but, one end is open so, 6a²-a²=5a²

Answer 2

Answer:

5a²

If 'a' is the side of cube.

Step-by-step explanation:

We know that a cube have six surface .

If the length of one side is ' a '.

Therefore total surface = 6a²
