Find the total area of the solid figure.
answers:
90 sq. ft.
126 sq. ft.
150 sq. ft.

Surface area = 126 square ft .

Step-by-step explanation:

Given : Rectangular cuboid .

To find : Find the total area of the solid figure.

Solution : We have given Rectangular cuboid .

Length = 3 ft .

Width = 5 ft .

Height = 6 ft .

Surface area = 2 ( l*w + w*h + l *h).

Plug the values

Surface area = 2 ( 3*5 + 5*6 + 3 *6).

Surface area = 2 (15 + 30 + 18).

Surface area = 2 ( 63).

Surface area = 126 square ft .

Therefore, Surface area = 126 square ft .

I'm pretty sure y is 5 because it shows that as the answer  i the grid listed beforehand.
