A cardboard box is open at one end and is shaped like a square prism missing one of its square bases. The volume of the prism is
Yuliya22 [10]
Given:
Volume of square prism = 810 cubic inches
Height of square prism = 10 inches

The volume of a square prism has this formula:
v = a²h

a = side length of the square prism
h = height

810 in³ = a² * 10in
810 in³ ÷ 10 in = a²
81 in² = a²
√81 in² = √a²
9 in = a

The length of each side of the base is 9 inches. Only 5 sides of the cardboard box has a cardboard because the 6th side is open.

I need help with properties of rhombus, rectangles and squares ​
Flauer [41]

Answer:

  • rhombus
  • x = 70
  • y = 5

Step-by-step explanation:

A quadrilateral with 4 same-length sides is a <em>rhombus</em>.

(If the corner angles are also 90°, then the rhombus is also a square. That is not the case here.)

__

Adjacent angles are supplementary, so ...

  x° = 180° -110° = 70°

Sides are the same length, so ...

  2y = y+5

  y = 5 . . . . . subtract y

_____

If part of the picture was cut off, the right side of the figure may be something other than 2y. If so, formulate the equation appropriately and solve for y.
