Answer:
Volume= 343 cm^3 and surface area =294 cm^2
Step-by-step explanation:
Volume of cube is given by the formula (length)^3
V= l^3
V= (7)^3
V=343 cm^3
Surface area is the area of all the sides
Area of one side = L^2
There are 6 surface so total surface area is 6 times the surface area of one side.
Area = 6 × (7)^2
= 6 × 49
= 294 cm^2
