What is the surface area of the 3 rectangles without the base of the triangular prism shown?

72 yd²

Step-by-step explanation:

From the question,

Applying

A = Lb+Lw+Lh Equation 1

Where A = surface area of the three triangular prism.

From the question,

Given: L = 6 yd, b = 4 yd, w = 5 yd, h = 3 yd

Substitute these values into equation 1

A = (6*4)+(6*5)+(6*3)

A = 24+30+18

A = 72 yd²

Hence the right option is 72 yd²

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

could you reply to this with the question so i can ?
