Answer:

A, 152 cm.

Step-by-step explanation:

A rectangular pyramid has a volume equation of

V = (lwh)/3.

Therefore, when we plug the values in:

[(7)(5)(13)]/3 = V

V = 455/3

V = 151.666667

V is approximately equal to 152 cm^3.

I hope this helped! :)

Neporo4naja [7]

Answer:

41.7m²

Step-by-step explanation:

As we can see, the area of this shape is simply the sum of 3 rectangles

Rectangle A has an area of 6 times 4 or 24m²

Rectangle B has an area of (3.8-2) times 3.5 or 1.8 times 3.5 or 6.3m²

Rectangle C has an area of 3 times 3.8 or 11.4m²

Adding that up gives 41.7m²
