Question

can i plz get all the formulas for surface areas and volumes of cube , cuboid , cylinder , cone , sphere and hemisphere !!..........

Answer 1

cube:
sa= 6x side²
csa=4x side²
volume= side³
cuboid:
sa=2(lb+bh+hl)
csa=4×lb
volume=lbh
cylinder:
csa=2pi r²h
sa=2pir×h+r
vol=pir²h
cone:
sa=pi×r×l+r
csa=pi×r×l
vol=1÷3×r²h
sphere:
sa=4×pi×r²
vol=4÷3×pi×r³
hemisphere:
sa=3×pi×r²
csa=2×pi×r²
vol=2÷3×pi×r³
