Answer:
The volume of the rectangular pyramid is 80cm³
Step-by-step explanation:
To calculate the volume of a rectangular pyramid we have to use the following formula:
v = volume
w = width = 8 cm
l = length = 6 cm
h = height = 5 cm
v = (w * l * h) / 3
we replace the values that we know
v = (8cm * 6cm * 5 cm) / 3
v = 80cm³
The volume of the rectangular pyramid is 80cm³

multiply top eqatyion by -1 and add to 2nd
9x-2y=24
<u>-x+2y=8 +</u>
8x+0y=32
8x=32
divid both sides b y8
x=4
sub back
-x+2y=8
-4+2y=8
add 4 to both sides
2y=12
divide both sides by 2
y=6

Answer:
25 meters.
Step-by-step explanation:
Given in the question that,
Initial depth of the submarine = 8 meters
After the order of the captain, the submarine was made to dive another 17 meters.
So, the final cruising depth of the submarine can be calculated by <u>adding the initial depth of the submarine and the depth further increased upon the order of the captain</u>.
Thus, final cruising depth of the submarine = 8 + 17 = 25 meters.
