The surface area of the Figure is 498 cm per square.
According to the statement
we have to find the surface area of the cuboid.
So, For this purpose, we know that the
Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape
And the formula become SA=2lw+2lh+2hw.
From the given information:
The length of the cuboid = 7cm
The width of the cuboid = 2cm
The height of the cuboid = 2cm
Use the formula which is
SA=2lw+2lh+2hw
Substitute the values in it
then
SA=2*7*2+2*7*2+2*2*2
SA=28+28+8
SA=64 cm per square.
And from another cuboid is :
The length of the cuboid = 7cm
The width of the cuboid = 7cm
The height of the cuboid = 12cm
Use the formula which is
SA=2lw+2lh+2hw
Substitute the values in it
then
SA=2*7*7+2*7*12+2*12*7
SA=98+168+168
SA= 434 cm per square.
Total area of figure = 434+64 = 498.
So, The surface area of the figure is 498 cm per square.
