K2. Calculate the total surface area of cuboids with the following dimensions (b) Length = 1.6 m, breadth = 80 cm, height = 120 cm

15360m3

Step-by-step explanation:

a=l*w*h

1.6m*80m*120m

=15360m3

→ 83,200cm²

Step-by-step explanation:

Given :

Length (L) – 1.6m

Breadth (B) – 80cm

Height (H) – 120cm

Convert Length into cm

1m → 100cm

1.6m → 160 cm

So, L → 160 cm

Apply Formula :

: Total surface area of Cuboid (T.S.A) :

→ 2 (160 × 80 + 80 × 120 + 120 × 160)cm²

→ 2( 12,800 + 9,600 + 19,200)cm²

→ 2( 41,600 )cm²

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine
