The amount of fabric that victor requires is about 158.4cm² (Option A). This is arrived at by using the theorem of 3-dimensional shapes.
What is the Formula for Getting the Surface Area of a Cuboid?
The formula for getting the total surface area of a cuboid is given:
A = 2(LW +H(L +W))
Plugging in the figures from the diagram (see the image attached), we have:
A = 2(4·1 +1/2(4+1)) = 2(4 +5/2)
Hence,
A = 2(4.1+2.5)
A = 13.2.
Recall that there are 12 of them, hence the total number of fabric required for all 12 will be:
A = 13.2 x12
A = 158.40cm²
