Plzzzzz help meee it's urgent.Plzzzzzzzzzzz.Rht answer give u a brainliest answer Plzzzzz help meeee...​

Answer 1

Answer:

a) diagram is a cuboid

$\bold{volume \: of \: cuboid = l \times b \times h}$

$\bold{ length = 4 \: } \\ \bold{ breadth = 2} \\ \bold{height = 4}$

$\bold{volume = 4 \times 2 \times 4 = 32 {cm}^{3} }$

b) diagram is a cube

$\bold{volume \: of \: cube = side \times side \times side}$

$\bold{side \: of \: cube = 3}$

$\bold{volume \: of \: cube = 6 \times 6 \times 6 = 216 {cm}^{3} }$

c) diagram is a cuboid

$\bold{volume \: of \: cuboid = l \times b \times h}$

l=5 ,b=1,h=1

$\bold{ = 5 \times 1 \times 5 = 25 {cm}^{3} }$

d) diagram is a cube

Volume of cube=side×side×side

side of cube=2

$\bold{ = 2 \times 2 \times 2 = 8 {cm}^{ 3} }$

Step-by-step explanation:

Hope it helps you

Answer 2

A)Given diagram is a cuboid

${volume \: of \: cuboid = l \times b \times h}$

${ length = 4 \: } \\ { breadth = 2} \\ {height = 4}$

${volume = 4 \times 2 \times 4 = 32 {cm}^{3} }$

B is a diagram of cube.

${volume \: of \: cube = side \times side \times side}$

$side \: of \: cube = 3$

${volume \: of \: cube = 6 \times 6 \times 6 = 216 {cm}^{3} }$

C is a diagram of cuboid

${volume \: of \: cuboid = l \times b \times h}$

l=5 ,b=1,h=1

${ = 5 \times 1 \times 5 = 25 {cm}^{3} }$

D is a diagram of cube

Volume of cube=side×side×side

side of cube=2

${ = 2 \times 2 \times 2 = 8 {cm}^{ 3} }$
