Explanation Given: The dimensions of the box as ( x − 7 ) , ( x − 7 ) and 8 and the volume of the box is 1800 cubic feet . Formula used: Square root property. If x 2 = a , then x = ± a for all real numbers a . The volume of a box is given by the continuous product of length, breadth and height. Mathematically, it is expressed as, V = l b h Here, l is the length, b is the breadth and h is the height of the box. calculation: Consider the box’s length and breadth as ( x − 7 ) feet and the height of the box as 8 feet . Write the expression for volume of a box. V = l b h V = ( x − 7 ) ( x − 7 ) 8 cubic feet V = 8 ( x − 7 ) 2 cubic feet But, the volume of the box is already given as 1800 cubic feet

Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

You are given a plane Π in R3 defined by two vectors, p1 and p2, and a subspace W in R3 spanned by twovectors, w1 and w2. Your task is to project the plane Π onto the subspace W.First, answer the question of what the projection matrix is that projects onto the subspace W and how toapply it to find the desired projection. Second, approach the task in a different way by using the Gram-Schmidtmethod to find an orthonormal basis for subspace W, before then using the resulting basis vectors for theprojection. Last, compare the results obtained from both methods
