The volume of a right triangular prism is 72 cubic feet. the height of the prism is 9 feet. the triangular base is an isosceles right triangle. what is the area of the triangular base? square feet what is the length of edge df?

Area of triangular Base is 8 feet² & Edge length is 4 feet.

Step-by-step explanation:

Given: Volume of Rectangular prism = 72 feet³

           Height of prism = 9 feet

           triangle of base is an isosceles right angled triangle.

To find: Area of Triangular Base & Edge of triangle

we know that,

Volume of Prism = Area of Base × Height

⇒ Area of Triangular Base × 9 = 72

Area of Triangular Base =

Area of Triangular Base = 8 feet²

Triangular Base is an isosceles right angled triangle .i.e., perpendicular legs are equal in length say x.

x = 4

Length of Edge = 4 feet

Therefore, Area of triangular Base is 8 feet² & Edge length is 4 feet.

the answer is 99.

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
