Question

lol A rectangular prism has a volume of 840 cubic inches. The height of the prism is 6 inches and the width is 10 inches. Find the length of the prism and explain how you found it.

Answer 1

Let’s call the two dimensions of the base x and y, the height we’ll just call h. So the formula of the volume of the box is:

x × y × h = 840 cubic inches

So, 2 ×x × 2 × y × h = 4 × x × y × h = 4 × 840 in^3 = 3360 cubic inches.

ur answer dear❤

Answer 2

Answer:

the length of the rectangular prism is 14 inches.

Step-by-step explanation:

height = 6 in

breadth (width) = 10 in

length = ?

we know the formula for the volume of a cuboid that is "l × b × h"

therefore l × b × h = 840 in³

⇒ l × 6 × 10 = 840 in³

⇒ l × 60 = 840 in³

⇒ l = 840/60

⇒l = 14 in

thus the length of the rectangular prism is 14 inches.
