Answer:
Te total surface area (TSA) of the cuboid is the sum of the area of its 6 faces
if the cuboid has width(w)=7 cm, Height (h)=3cm., length(h)=5cm
A=lw=5*7=35 cm²
A2=hw=3*7=21
A3=lh=5*3=15
TSA=2(lw+hw+lh)
TSA=2(35+21+15)
TSA=2(71)=142cm²
volume of the cubiod=l*w*h
V=lhw
V=7*5*3= 105 cm³
the length of an edge of this cube:
since it is a cube then all sides are equal l=w=h
√105= 10.247 ( rounded to the nearest hundredth)
