Answer:
400 cm² of stickers
Step-by-step explanation:
A wooden box has the shape of a rectangular prism.
To solve for the above question, we would be using the formula for the Surface Area of a rectangular prism to calculate how much stickers are required .
The formula for the surface area of a rectangular prism =
A=2(wl + hl + hw)
l = Length = 20cm
w = Width = 4cm
h = Height = 5m
Hence,
= 2 × (4 × 20 + 5 × 20 + 5 × 4)
=400 cm²
Therefore, 400cm² of stickers would be needed to cover the wooden box.
Answer:
x=12m
Step-by-step explanation:
44 divide by 3 2/3 = 12
The answer is MN and QR are similar of corresponding triangles !!

Price of
Computer(C) + Printer(P) + Scanner (S) = $2543
Price of Computer:
C = 1502 + P
Price of Printer:
P = 123 + S
So Price of computer now becomes:
C = 1502 + 123 + S (Here we replace P with 123 + S)
It is Algebra from here:
C + P + S = 2543
(1502 + 123 + S) + (123 + S) + S = 2543
1748 + 3S = 2543
3S = 2543-1748
3S = 795
S = 795/3
S = 265
C = 1502 + 123 + S
C = 1502 + 123 + 265
C = $1890
