Question

answer soon..........3 nd 4

Answer 1

answer for the 3rd question is 240 cubes

Answer 2

3rd) Volume of cuboid= l×b×h
= 16cm×10cm×6cm
= 960cm^2

Volume of cube= (4cm)^3=64cm^3

Number of cubes can be cut= 960/64
= 240/16=60/4= 15

4th)14 cm becomes curcumfernce=
$circumference = 2\pi \: r$
14cm=2×22/7 ×r
14cm×7/44= r
2.2 cm=radius

$volume = \pi {r}^{2} h$
V=22/7 × 2.2×2.2×25
380.3cm^2= volume


$hope \: it \: helps$
