Answer 1

Answer:

240 cm^3

Step-by-step explanation:

The solid is composed by two rectangular parallelepipeds. To find the total volume  we have to find the volume of the two solids and added up.

To find the volume of a parallelepiped we have to use this formula:

V = base surface x height

The area of rectangle is : base x width

So:

Area first rectangle: 4 x 6 = 24 cm^2

V = 24 x 7 = 168 cm^3

Area second rectangle: 4 x 2 = 8 cm^2

V = 8 x 9 = 72 cm^3

total volume = 168 + 72 = 240 cm^3
