Question

can sombody help a brother out :P uwu

Answer 1

Answer:

Step-by-step explanation:

Surface area of a cuboid =2(lb+bh+hl)

=(4×4+2×4+4×2)2

=(16+8+8)2

= 32×2

= 64cm^2

Answer 2

Thanks for question!!

From the given figure we conclude that it is a cuboid.

Given:-

Length= 4 cm

Breadth= 4 cm

Height= 2 cm

Since,the Formula of cuboid are:-

1)

$volume = l \times b \times h$

2)

$c.s.a = 2 \times (l + b) \times h$

3)

$t.s.a = 2 \times (lb + lh + bh)$

Since,we have to find Surface area so we use t.s.a of cuboid..

Now, putting the value of l,b,h in given formula..

$2 \times (4 \times 4 + 4 \times 2 + 4 \times 2)$

$2 \times (16 + 8 + 8)$

$2 \times (32)$

${64cm}^{2} ans....$

hence , S.A of cuboid is 64 cm2

you can use other formula to find its volume,C.S.A. and so on if the h,b,and l is given.
