Which equation can be used to find the volume of this solid 7in 11in 9in

The volume of the solid is either 346.5 in³ or 693 in³.

Step-by-step explanation:

The solid can either be a triangular prism or a rectangular cube.

The volume of a triangular prism is:

Here,

B = base

H = height

L = length

Let,

B = 7 in

H = 9 in

L = 11 in

Compute the volume of a triangular prism as follows:

Thus, the volume of a triangular prism is 346.5 in³.

The volume of a rectangular cube is:

The values of L, B and H remains the same as above.

Compute the volume of a rectangular cube as follows:

Thus, the volume of a rectangular cube is 693 in³.

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
