Question

this is rly imp for my home work

Answer 1

Step-by-step explanation:

Given: Dimensions of herbarium:

1 = 30 cm, b = 25 cm, h = 25 cm

i) Area of the glass=Total surface area of herbarium

= 2(lb + = bh + Ih)

= 2(30×25 + 25×25 + 25×30)

= 2(750+625+750)

=2×2125

=4250cm²

(ii) herbarium in in the shape of cuboid.

So Length of the required tape will be equal to total length of edges of cuboid.

Length of the tape= 4(1 + b + h)

= 4(30 + 25 + 25) = 4x 80

= 320 cm.

Tape needed for all the 12 edges=320 cm
