I hope my answer has come to your help. God bless and have a nice day ahead!
Surface area of the prism is 2xy+2xz+2yz
I think, we can cut hole on the face of the prisma 40x30, and size of the whole will be 5X5X5
hole increases surface area. If side of the cube is "a", then a^2 is the area of the one face of the cube.
when we are doing the hole, we remove 2 faces and add 4 more faces, so
2xy+2xz+2yz-2a^2+4a^2= 2xy+2xz+2yz+2a^2
So, 2*5*40+2*5*30+2*40*30+2*5^2=3150 cm^2
i hope it helps, it is what i can come up with now
Answer:
$9.75
Step-by-step explanation:
To get from 4 to a dozen, you have to multiply by 3.
3.25 x 3 = 9.75
Look to the right of the number with the line under it. If it is 5 or up then the number with the line goes up by one.
