Question

Can someone help me with this? Please :)

Answer 1

Answer:

12

Step-by-step explanation:

the lenght is y, the width is also y since the base is a square and since the height is twice the lenght it will be 2y, knowing that we just find the total surface area in terms of y.

which would be: 2(y·y) + 2(y·2y) + 2(2y·y)=360

this then simplifies to=  10y²=360

                                  = y²=36

                                  = y =6

the height therefore is 2y meaning its 2(6)=12

this problem was rather easy its so sad no one helps out in here totally hate this site wish more people helped
